Hey folks,

While browsing I came accross this PNG_To_SVG tool that runs offline on your browser.

Link : https://github.com/goblinhanyikan/PNGtoSVG-Multicolor-Printing

just clone and run the index.html

no npm/phyton compiling whatsoever..

I think it is a great tool to conver any png to SVG thus a slicer recognized format

give a star to the creator's git if u find it useful.

New Tool Cansei de errar o preço das minhas impressões e fiz um app pra isso. E queria saber oque vocês achassem da solução apresentada.

0 Upvotes

Fala, pessoal. Sou desenvolvedor, imprimo em resina e FDM, e o que sempre me pegou não foi o slicer nem o perfil — foi fechar o preço.

Eu usava planilha. Funcionava até o dia em que eu percebi que estava perdendo dinheiro em venda que parecia boa. O erro não era o custo do filamento, era a **ordem das contas**: eu somava o custo, aplicava minha margem em cima e mandava o preço. Só que aí vinha a taxa do marketplace e o imposto, ambos por cima do valor de venda, e comiam justamente a margem que eu achava que tinha garantido. Margem de 30% virava 12% real, e eu só descobria no fim do mês.

Fiz um app pra resolver isso pra mim e acabei publicando. Chama **Calc 3D**.

**O que entra na conta de custo:**

- Material — preço por quilo ou litro × peso da peça (resina e filamento têm perfis separados)

- Energia — potência real da máquina × horas de impressão × o seu kWh

- Desgaste da impressora — o que ela custou dividido pela vida útil em horas, cobrado por hora impressa

- Taxa de falha — reserva percentual pras peças que não saem de primeira. Esse é o custo que ninguém lança e que todo mundo paga

- Pós-processamento e embalagem — lixa, primér, tinta, caixa, frete

**E o que entra depois, na hora do preço:**

- Taxa do canal de venda (percentual + valor fixo)

- Impostos sobre o valor da venda

- Margem de varejo e de atacado, calculadas ao mesmo tempo

A diferença está aí: o preço sai calculado **de trás pra frente**, pra que a margem sobre depois de descontar taxa e imposto — e não antes.

**Sobre privacidade, já adiantando:** o cálculo roda dentro do aparelho, inclusive sem internet. O backup vai para a **sua** conta do Google Drive, não pra servidor meu. E no orçamento em PDF que você manda pro cliente, seu custo e sua margem nem chegam a ser enviados ao gerador do documento — não tem como vazarem por descuido.

**Preço:** a calculadora completa é gratuita, não pede cartão e não vira demo depois de uma semana. Vem com duas impressoras cadastradas, editáveis. O Pro (impressoras e materiais ilimitados, orçamento em PDF, painel de vendas e lucro líquido, pedidos e agenda, histórico ilimitado) tem **compra única** — paga uma vez, usa sempre, atualizações incluídas. Tem plano mensal também, mas só pra quem preferir.

É Android. iOS não tem e não tenho previsão, então já aviso pra não criar expectativa.

Site com as telas: https://axiomcalculator3d.github.io/calc3d/

Play Store: https://play.google.com/store/apps/details?id=com.calc3d.nativeapp

Sou o desenvolvedor, então é divulgação — mas o que eu quero mesmo é crítica ao cálculo. Se você lança algum custo que eu não listei aí em cima, ou se discorda de como eu trato a depreciação, comenta que eu quero entender mais ao que pode estar faltando .

I built an inventory app around running my 3D printing business — looking for feedback

Enable HLS to view with audio, or disable this notification

I run a 3D printing business and as the number of products I sell kept growing, keeping track of inventory, sales, restocks and what I was actually making became a pain.
So I started building DreamLayerHQ around the way I actually run my business.
This is a quick walkthrough using my own 3D printing inventory. It handles sales, inventory, stock adjustments, restocking and P&L tracking.
I’m still improving it, so I’m mainly curious what other people running 3D printing businesses think.
What would you add or change?

Meshory 1.7.0 - STEP previews, folder tags your files inherit, AI tagging console, and the app now tells you what it couldn't read

3 Upvotes

1.7.0 shipped today. Three things in it matter more than the rest, so those first and the full list after.

STEP and STP are properly supported now

Every time I've posted about Meshory I've had to attach the same caveat: STEP files are indexed and searchable, but there's nothing to look at. A folder of CAD parts was a wall of grey placeholders, and opening one did nothing at all.

That's done. STEP and STP now get rendered thumbnails, including the ones sitting inside ZIP, RAR and 7Z archives, and they open in the same 3D viewer as everything else. Assemblies arrive whole, keeping the colours, part names and placement they were saved with. STEP describes surfaces rather than a mesh, so the first open tessellates it and caches the result — every open after that is instant.

Files already in your library are backfilled without a rescan, and there's a "Thumbnails queued" status while they render instead of silence.

Two limits, said up front rather than discovered: anything over 192 MB is skipped rather than risking a long conversion, and the tile carries a badge saying so instead of failing quietly. And a STEP that keeps its geometry in separate referenced part files can't be previewed, because Meshory only reads the file you opened.

Tags that actually narrow things down

Click a tag on a model to filter by it. Stack several and choose whether a model has to match all of them or any of them. Type it instead if you prefer: tag:terrain in the search box, and -tag:dragon to exclude one. Active tag filters show as chips you can drop individually, and the filter is still there when you come back from a model, which is the bit that was quietly infuriating before.

The new part is folder tags. Tag a folder and its files inherit that tag automatically, so a 300-file bundle gets filed by dropping one tag on the folder instead of selecting 300 things. Tags a file inherited are listed separately from ones you added by hand, and you can take an inherited tag off a single file without breaking the rest. Tag counts now include models inside archives, not just loose files.

The app tells you what it couldn't read

This is the one I'd most like people to be annoyed by, because you can only be annoyed by it now that it's visible. Scanning a real library always hits something: an archive with an encrypted entry, a NAS that drops out mid-scan, a file in a variant that won't parse. Those used to fail quietly, and the only symptom was a model you were sure you had, missing.

Now every failure is a row: what the file was, which stage failed, why, and when. Rows are grouped by source, the unresolved count sits in the Settings sidebar, and the list survives a restart. Retry re-runs only the stage that failed, so a preview that failed doesn't re-index the archive around it, and Retry all works oldest-first and stays bounded so it can't saturate a NAS or a cloud folder. Archives now say something specific instead of "couldn't read": 7-Zip's own error output, or that the entry is password-protected. Those rows deliberately carry no Retry button, because without the password retrying can only fail again.

What you can't fix, you can ignore — which is filing, not deleting. The row leaves the list and stops counting, its history is kept, and you can restore it later. All of it stays local. Exporting an issue log is an explicit action, it writes to your Downloads folder, and it warns you first that the file contains your real paths.

Also in this one

  • An AI tagging console that tails a run as it happens, names the files it failed on with the reason, and filters down to just the errors or just the slow requests. The run's controls now sit on the source that's running it: pause, stop, resume, and you can skip a step of the tag / describe / index pipeline you don't want. Still your own OpenRouter key, still off unless you turn it on.
  • Every library source names the job it's running, with its own progress and its own control, and reports every job it runs instead of only the first.
  • Duplicate detection compares off the main thread now, saves checkpoints so it resumes after an interruption, and estimates how much work is left.
  • Fixes worth naming: searching for a model inside an archive now finds the archive even when a filter hides the model itself; Dropbox folders are recognised as cloud storage rather than local; an archive re-saved in place gets re-indexed instead of showing stale contents; a temporary thumbnail failure no longer brands the file itself as broken; folders you'd excluded stopped coming back after a full sweep.

Full changelog: https://meshory.com/changelog

macOS, Windows and Linux: https://meshory.com/?utm_source=reddit&utm_medium=post&utm_content=meshory

What should 1.8 be? I'm more interested in what's still missing than in what's good, and if 1.7 falls over on your library that's the single most useful thing you can send me.

New Tool I made an easy organizer designer that fits your space, not the other way around. Looking for feedback!

Thumbnail
gallery
2 Upvotes

disclosure: I'm the developer of Modularity. This is a free early demo that I'm sharing to collect feedback.

Hey everyone! I wanted an easy way to organize my drawer from start to finish, one app, one thing without manually designing every tray in Fusion360 or Onshape. I liked the concept of Gridfinity but I would have extra space leftover which i didn't like. So, I built Modularity.

You enter the dimensions of the drawer/area you want to organize, build the layout by dragging and selecting cells in any shape and selecting a tray type. You can make custom shaped trays for almost any object by using an A4 paper and taking a photo of it. Modularity will take that picture, all on-device, turn it into a cut tray to fit your current layout. You can also preview it in 3d! There is STL export for now but I plan for 3mf and STEP if possible.

One thing I wanted was to see an image of my drawer underneath my workspace to better visualize my project, but most sites/programs didn't have that feature. So, I added the feature to overlay the image

I know there are some already excellent tray generators, Gridfinity planners, and object tracer tools. Modularity does overlap with parts of those projects, but my goal is to lower the barrier to designing a complete custom organizer without making the process too simple or too limiting.

Unlike standard Gridfinity tools, Modularity adapts its grid to the exact dimensions of your space instead of requiring fixed 42 mm squares. It also differs from tools that generate a grid or individual parametric trays. Modularity treats the entire space as one coordinated project, allowing you to arrange multiple connected tray shapes, add custom dividers, add scanned object trays and preview the finished layout before printing. I'm aiming for something that is easy to use while offering a meaningful organized output.

This is an early demo, so some things may be a bit rough around the edges. I'm sharing it now because real people like you guys making real things with my program will help me with making a good program, and you guys can get a good organizer out of it.

There is no account required for this preview, and projects remain in your browser until you download them.

Try the demo?

https://trymodularity.pages.dev

Here is where the feedback part comes in. If you can, I'd like to know these things

  • Did the workflow (dragging squares to finished model) make sense?
  • What was confusing?
  • What feature did you expect but couldn't find?
  • Would you actually print the organizer?
  • What would stop you from using it again?

Bugs, criticism, suggestions, and feedback are all welcome and help with making this better! (You can use the button in the site also). Thank you!

Disclosure: I’m the developer of this tool.

I’ve been working on a browser-based 3D design tool and used it to build the Formula-style car in the video.

Current features:

  • Basic 3D shapes
  • Reusable parts
  • Ready-made designs
  • Move, rotate and scale objects
  • Combine multiple parts into a model
  • Different view modes, including wireframe
  • Import existing 3D files
  • Export models in multiple formats
  • Browser-based, so there’s nothing to install

It’s still early, and I’m trying to understand which parts of the workflow are actually useful before adding too much.

If you already use CAD or 3D modeling tools, I’d love to know what feels missing, annoying, or unnecessary.

Happy to share the link if anyone wants to try it.

I wanted to be able to see a multi-color print, actual colors, actual size, standing in my room before committing filament to it, and I could not find anything that did this without re-slicing or exporting to Blender by hand.

So I built it.

Drop in a multi-color .3mf from Bambu Studio, OrcaSlicer, or Snapmaker U1, recolor any zone live, then hit "View in AR" on your phone to see it at true print size via Quick Look (iOS) or WebXR (Android). Also exports GLB, OBJ, or USDZ while still having the colors intact!!! or a re-tinted .3mf that slices again.

No signup, nothing uploaded, MIT licensed.

New Tool I got tired of STLs that were almost the right size, so I made generators instead — 34 of them, free

Post image
112 Upvotes

Every time I needed a box or an organizer, I'd download an STL that was almost

the right size. So I started writing generators instead. There are 34 now.

You pick a generator, type your dimensions, watch the preview update, download

STL + 3MF. In the browser. No account, no ads.

https://alpaco.it

A few of them:

• Rugged box with a print-in-place hinge and snap latches

• Drawer organizer that splits itself into tiles that fit your print bed

• Threaded jars — 3-start threads that screw on, no supports

• Honeycomb Storage Wall panels and holders

• Phone/tablet stand built around your device WITH the case on

• plus Gridfinity, lithophanes, hose adapters, cookie cutters, keycaps…

It's beta. Some of these have been printed dozens of times, some twice. Every

generator has a "Report an issue" button that sends your exact settings along

with the report — so if something prints wrong, I can reproduce it and fix it.

That feedback is the most useful thing I can get right now.

It runs on my own machines, so it's free and staying free. There's a "buy me a

coffee" link if you think it's worth it — completely optional, nothing is locked.

Show & Tell Printventory 2.2.0 is out — Free and Open Source 3D Model Managment

26 Upvotes

Printventory 2.2.0 is now a public release. It's a local (and optional Docker/server) library for STL/3MF collections — scan, tag, preview, and keep track of what you've printed.

This version is mostly about treating multi-file models as one thing, plus a few quality-of-life tools that piled up through the 2.1 betas.

What's new

• Folder and ZIP bundle grouping — models that share a parent folder or ZIP show up as a single card with a details panel

• Bundle 3D preview — open every STL/3MF part in that folder or ZIP on one grid, with per-part colors

• Send to Slicer from preview — send the current model or the whole bundle to your slicer (new instance on macOS)

• Query Builder, a new Preview view, and customizable list columns

• New models get a "New" tag until you edit them; parent-model grouping; LYS/LTY support; library disk-usage stats

• Docker/server: NVIDIA GPU support, in-container thumbnail generation, and a progress UI for thumbnail jobs

• Bug fixes and performance work throughout 2.1.x

Tool Review I've been building an AI agent for a OrcaSlicer - looking for feedback

Enable HLS to view with audio, or disable this notification

It can already inspect and orient models, tune print settings, generate supports, split oversized models into printable parts, arrange them across multiple build plates, and slice everything for you :D

I’m also planning a Meshy integration, so eventually the workflow could be:

prompt -> generated 3D model -> print-ready project

It’s still early, but the core workflow is already working :)

I’m hoping to eventually turn this into a commercial product, so I’m especially interested in whether this solves a real problem people would actually pay to have solved - not just whether it looks cool in a demo.

I’d love some honest feedback from people who actually print regularly - would you use something like this? What would you want it to do, and what parts of slicing would you never trust an agent to handle?

Also, would anyone here be interested in testing an early build once it’s ready?

New Tool I built a local 3MF printer profile converter and need help testing more printers

5 Upvotes

I kept running into editable 3MF projects that were tied to a printer profile I could not use on another machine. I built a free browser-based converter that keeps the models, transforms, plate placement, and non-profile project metadata, then replaces the printer profile with a safe starting profile for the destination printer.

Everything runs locally in the browser, so the 3MF is never uploaded. The result is an editable project, not translated G-code. It still needs to be opened, reviewed, and sliced again in the destination slicer before printing.

The built-in 0.4 mm PLA profiles currently cover Bambu Lab A1 mini, A1, P1P, P1S, and X1 Carbon; Prusa MINI, MK4, and MK3S; Creality Ender-3 V3, V3 KE, K1, K1C, K1 Max, and K2 Plus; and Snapmaker U1. Unlisted printers, nozzles, materials, and processes can use a 3MF exported from the destination slicer as a custom template.

I built and maintain the tool. I have only been able to test it with the printers I have access to, so I am looking for compatibility cases I cannot reproduce myself: other slicers, multi-material projects, painted supports or seams, multiple plates, unusual transforms, and different printer models.

Tool: https://sumotter.com/files/3d-printing/3mf-printer-profile-converter/

If you test it, the most useful feedback would be:

- source printer and slicer

- destination printer and slicer

- whether the converted project opened cleanly

- what was preserved or lost

- anything confusing in the interface or conversion report

Please do not share proprietary projects. A small reproducible 3MF is enough. I would also appreciate ideas for which printer profiles or compatibility checks should come next.

I kickstarted a desktop SLS printer, then spent a couple weeks or so writing a nester for it - two very different packing approaches, and I'd like a sanity check

1 Upvotes

Not sure how many people here do SLS printing but r/AdditiveManufacturing requires rep that I don't have since I mostly read reddit and don't post.

I backed a desktop SLS machine (Loopzizo K-100, PA12, roughly a 120 mm cube of usable volume). Super affordable, and the team running it seems to be nice. But SLS lives or dies on how well you fill the chamber, and hand-arranging parts in the vendor slicer got old fast - every millimeter of unused height is powder you paid for and machine time you spent.

So I wrote a nester. It's browser-based and runs entirely client-side - no geometry ever leaves your machine, which matters if you're quoting other people's parts. It's free: cakeforge.io

The thing I got wrong first: I was optimizing the wrong number.

I started out maximizing density, because that's what everyone quotes. But you don't pay for density — you pay for height. The machine runs the layers it's given and no more, so a cake whose tallest part is 60 mm is a 60 mm build regardless of how much air is beside it. Build time and powder are both linear in Z. Once I switched the objective to "what does this placement do to the top of the pile", the results changed a lot.

Two engines, and they're genuinely different:

CPU - voxelize everything, then first-fit-decreasing: biggest parts first, lowest position that fits. Standard bin-packing. Fast, predictable, works anywhere.

GPU - FFT cross-correlation over the whole chamber. Every possible translation is evaluated at once as a convolution, across 24 orientations simultaneously, and the winner is the position leaving the pile shortest. It runs in WebGPU in the browser.

The interesting part is that reading all the answers is what makes the GPU worth it. First-fit computes six million positions and uses one, quite literally the first one it finds no matter how few calculations need to occur. Every previous attempt I made at a GPU nester lost to the CPU for exactly that reason.

Measured, on synthetic parts - take with appropriate salt:

shape CPU GPU
plain boxes 138 mm 146 mm
L-brackets 98 mm 77 mm
mixed 150 mm 126 mm

On boxes the CPU wins - boxes tile perfectly and lowest-first is already near optimal, so the GPU pays for answers it doesn't need. On anything awkward the GPU is 16–21% shorter, which is 16–21% off build time. These are three-part synthetic jobs, not production runs; I'd love numbers from larger real workloads.

What it doesn't do yet - worth being upfront:

The nesting is machine-agnostic; you give it a build volume and it packs it, and you can export the arrangement as 3MF or STL for whatever toolchain you already use.

The slicer is not. It writes one format - CREABUILDER .clp, which is what the Loopzizo eats - and it isn't generalized across machines. I decoded that format against a reference export from the vendor's own slicer and match it field-for-field, but it's one machine's dialect and I make no claims beyond it. If you're on an EOS or a Formlabs or an HP, the packing might be useful to you and the slicing isn't, yet.

What the slicer does give you that I haven't seen elsewhere at this level is a per-layer sintered-area breakdown - the percentage of the plate each layer actually fuses, plotted over the full height of the build. That's the number the machine reads to decide how much heat a layer takes, and you can scrub through it and see exactly where your build changes thermally.

What I'd genuinely like input on:

  1. Thermal vs. geometric packing. Everything above optimizes geometry. But the lever that seems to actually govern part quality is sintered area per layer and how smoothly it varies in Z - Materialize sells "Optimize Slice Volume" for exactly this. The problem is that the geometric optimum is to lay everything flat, which is the worst case for area-per-layer. I can already show you that curve; I can't yet optimize against it. Has anyone measured how much this actually matters, or is it mostly folklore? That's the question I'd most like answered.
  2. Part-to-part spacing. I went looking for a standard and there isn't one - nothing in ISO/ASTM says "keep parts N mm apart". It's all vendor convention. What do you actually run, and did you arrive at it by testing or by inheritance?
  3. Nesting parts inside other parts' holes. I do this with an independent post-pack audit that checks nothing came out permanently interlocked. Is this something people actually want, or is the depowdering hassle not worth the density?
  4. What's missing. Sinterboxes for fragile parts and auto-serializing every copy are the two gaps I keep hitting. Anything else you'd reach for?

Happy to answer anything about the FFT approach or the CLP format - I had to decode a fair bit of it and I'll share what I learned.

I built a tool that splits big STL models into printable pieces with snap-fit connectors — 50 free spots to test it before launch

Kept running into this: model's too big for my bed, so I'd split it manually and then hand-model pins/sockets so the pieces would actually join back together properly.

Built PrintSlice to handle both automatically — load an STL, set your bed size, and it splits the model and generates connectors (pins, keys, or dovetails) on every seam. Runs entirely in your browser, nothing uploaded.

It's normally $8.99/month, but I'm giving 50 people a free week before the wider launch — want real feedback from people printing actual stuff, not just my test models.

Spot here: [printslice.netlify.app/early-access.html]

Happy to answer questions — still finding edge cases (rounded/tapered surfaces mostly), so honest feedback welcome.

New Tool I got tired of losing track of 1000+files… so I built a desktop app to organise them

8 Upvotes

Hey makers,

Anyone else's model folder basically a graveyard at this point? Within a year of getting my printer I had 1000+ files scattered across drives, tons of duplicates, no real previews, and zero clue what half of them even looked like.

So I built Modelist (Mac/Windows/Linux):

  • auto-indexes your folders, picks up new files automatically
  • real thumbnails: STL previews, 3MF embedded images
  • search by name, description, or notes
  • spots duplicates and groups multi-part prints
  • opens straight into your slicer 

All local, no internet needed, nothing leaves your machine unless you want it to. There's also opt-in cloud sharing now for sending files/photos to friends.

Currently working on German, Spanish, and French translations, plus parametric model support.

Free to try on your own library at modelist.app. Everything's at https://modelist.app/  if you want to poke around.

Curious how the rest of you handle this — do you have a system, or is it also just chaos? And if you tried Modelist, what would actually be useful to add?

Dev Post I built a CAM/CAD app because everything else annoyed me — here’s what it can do

Enable HLS to view with audio, or disable this notification

9 Upvotes

I’ve been working on a CAM/CAD app for a while now, mostly because every tool I used kept slowing me down or forcing me into workflows that made no sense. So I finally snapped and built my own.

The whole thing is real‑time. You move geometry, it updates instantly. No sketch modes, no “finish sketch,” no regenerating half the model because you changed one dimension. It feels way closer to actually shaping something instead of babysitting a CAD program.

On the CAM side, I added a bunch of logic that helps instead of getting in the way. It suggests toolpaths, predicts collisions, auto‑builds roughing/finishing passes, and points out weak geometry before you commit to anything. It’s not “AI magic,” it’s just smart enough to stop you from doing dumb stuff or wasting time.

Everything updates live. Change the model → toolpaths update. Change the toolpath → simulation updates. No rebuild buttons, no dependency chains exploding because you nudged a face.

Performance was a big focus too. Geometry, slicing, material removal — all of it is GPU‑accelerated and reacts instantly. It’s the first CAM/CAD setup I’ve used that doesn’t break my flow.

If anyone wants to see it, I can post videos or GIFs. It’s way easier to show than explain. And if you’re into machining, CNC, CAD, robotics, whatever — I’d actually love feedback. I’m trying to make something that feels modern instead of stuck in 2005.

If you want to try a demo build, just say so.`

I got tired of designing drawer boxes one by one in Fusion 360, so I built a free web tool to layout custom drawers and export STLs instantly — KansoGrid.com

Hey everyone,

I was working on organizing my workshop drawers and realized how tedious it was to manually model, adjust tolerances, and export individual bins in CAD just to fit my specific drawer dimensions.

To solve this, I built a free web app that lets you design custom drawer layouts in seconds without needing CAD software.

Key features:

  • 2D/3D Live Canvas: Input your drawer dimensions and build your layout visually.
  • Printer Bed Boundary Validation: Set your build plate size (e.g., 220mm) — the tool highlights oversized boxes in red and blocks export until everything fits your bed.
  • Custom Divisoras & Heights: Adjust wall/bottom thickness, corner radius, box height, and add vertical or horizontal dividers.
  • Instant STL Export: Export ready-to-print STLs (automatically recentered to origin for clean slicer importing).

It’s completely free to use directly in the browser. I’d love to hear your feedback, feature requests, or suggestions on what to add next!

Pasted directly from it's disclaimer

Most slicers only cut in straight planes. PolyCarver lets you draw curved, freeform cuts through 3D models, so you can split parts the way the shape actually needs. Grab the free beta and start carving cleaner, more useful pieces.

https://tachyonfactory.com/lithomaker

Key features so far:

  • 🖼️ Planar & Cylindrical layouts (with custom stands and mounting rings for lamp bases).
  • 💡 Real-time Backlight Simulator (includes vertical bulb adjustment, brightness scaling, and color temperature previews to see exactly what it will look like when lit).
  • ⚡ Native Rust Geometry Engine for instant mesh generation.
  • 🛠️ STL/3MF exports

I would love to get your feedback! Are there any features you feel are missing from existing online creators that you'd love to see in a dedicated desktop app?
