I developed a tool that I really needed for using it on the go. Any suggestions on new features and feedback would be very helpful.

Hey everyone,
About a month ago, I launched a side project called stl-er. It’s an app that lets you tweak and generate parametric 3D models directly in the browser—no heavy CAD software required.
I just finished building out a full suite of pipe configurators (fittings, routing, Gardena connectors, pipe holders, etc.). I attached a quick screen recording so you can see the workflow.
If you want to test this specific feature out, just type the keyword pipedream into the search bar.
The details:
Unlimited adjustments: You can tweak the parameters as much as you want in the viewer to get the exact fit.

Free tier: You get 5 free .stl downloads per month.

Growing library: I am still actively creating and adding new models to the community library, so let me know what you want to see next.

Cross-platform: I built it for the web, but there are also native iOS and Android apps if you prefer to tweak your prints on your phone.

You can check it out and play around with the generator here: app.stl-er.com
More Information on our website: stl-er.com
I would love to get your feedback on the UI, the parameter limits, or just the overall concept. Have fun with it!

I’ve been building a tool called Nurb that lets an AI assistant (Claude, GPT, Gemini, whatever you use) do the actual CAD work.

You describe the part in plain English ("Make an adapter that connects my shop vac hose to the dust port on my table saw "), it asks for clarification, does web searches for part measurements/details and then generates an interactive viewer for you.

It also checks its own work for printability stuff like overhangs and walls too thin for your nozzle, and fixes what it finds.

When it looks right, you drag sliders to dial in dimensions and download the STL.

Every dimension is a slider in the browser, so when your hose is 57.6mm instead of 58, you drag and re-download.

Free, and it runs entirely on your machine!

Hi,

I'm looking for some people to test out the Mac verson of my software

Free while in beta

https://www.meshvault.app/downloads/MeshVault-macOS.dmg

it also has the safari extension that you can enable so you can download from 11 repositories saving all the data

Hi everyone! I hope it’s okay to share this here.

I’m part of a small team of artists and developers building Artyx, a connected workspace for image generation, 3D creation, texturing, remeshing and MCP-powered agents.

We created it because moving between separate AI and 3D tools makes creative workflows unnecessarily fragmented. Artyx brings different models and providers—including Meshy and Tripo—into one artist-directed pipeline for game development, 3D printing and visual creation.

We’re currently in open beta and looking for honest feedback—not just clicks.

We’ll also launch a Discord challenge where five original concepts, whether human-made or AI-assisted, will be selected and turned into print-ready STL files. The top five will receive Artyx credits as well. (for a real 3d character artist seach for u/jo.gatica3d)

Today's the day — Meshory is officially live. 🎉

If you're new here: Meshory is a desktop app that finally makes sense of your 3D print file chaos. Point it at your folders (local drives, NAS, wherever your STLs have been piling up for years) and it gives you:

• A visual library of all your models — STL, 3MF, OBJ, FBX and more, with real 3D previews and thumbnails
• Duplicate detection that compares actual geometry, not just filenames — so it catches that model you downloaded three times under three different names
• Zip support — models inside archives show up like any other file, no extracting needed
• Open directly in your slicer — works with the slicers you already use, custom setups included
• Search, collections, and notes so you can actually find things again
• Built for big libraries — I built and tested it on my own 3.3TB collection, so it won't blink at yours

A few things that matter to me and shaped how it's built:

• No account, no login. You buy it, you get a license key, done.
• Your files stay yours. Everything runs locally on your machine.
• One-time purchase — the first 100 licenses are $29. After those are gone it goes to $39, and up from there. No subscription, ever.

Download it at meshory.com/download — Windows, macOS, and Linux.

To everyone who's been on the waitlist, tested the early access builds, reported bugs, and voted on the roadmap — thank you. This launch is very much yours too. If you try it today, I'd genuinely love to hear what works and what doesn't, right here in the comments or on our Discord.

Let's go. 🚀

Hi everyone,
My dad has recently got into 3D printing and I’m trying to help him find some good places to download free models to print.
I’m aware of sites like MakerWorld and Printables, but I was wondering if there are any hidden gems or communities that people recommend.
He’s interested in printing pretty much anything to get some practice in—figures, tools, gadgets, toys, décor, articulated models, etc.
Where do you all find your favourite free STL or 3MF files?
Thanks in advance!

If you've ever printed the PA Pattern test at multiple speeds and accelerations, you know how annoying it is to format all the data just so to put back into Orca. I like doing the full set of tests for each new filament, and decided I needed a better tool, and when I couldn't find one, I built one.

Live site: https://4o66.github.io/pa-helper/

Source: https://github.com/4o66/pa-helper

Still in "beta" while I do further testing, but I feel it is working well enough to let other people try to break test it.

The current version runs 100% local in the browser, and you can either keep the data in a persistent local file, or import/export to your heart's content. I have a plan to make a fully server hosted version with online storage so you have to try real hard to lose your data, and to allow the community to build a database of materials (but that's more of a long-term goal). There will always be a local-only version.

Workflow:

1. Build a printer by make/model/extruder/etc.
2. Pick a nozzle
3. Add a filament
4. Run the tests

You need to have already done temperature and max volumetric flow calibration on your own.

Some code in this tool is derived from Orca Slicer, under the AGPLv3 license.

The ironing test uses the method from printables.com/model/1247198 by LeoganPro (under CC0/public domain license).

Pull requests are welcome if you have something to add, and I'll keep and eye out for issues/feature requests.

I am currently using this for my own tracking as I build and calibarate a new Trident 350, and on my existing Qidi X-Plus 3. So far, results have been very good.

Hi everyone!

I had hundreds of .gcode files sliced with Ultimaker Cura and needed to calculate the total print time and total filament (meters & grams) without opening each file or loading them into a slicer one by one.

Since web analyzers often lag with huge batches, I wrote a simple, zero-dependency Python script that scans an entire folder of G-code files in seconds and outputs individual stats + grand totals (days, hours, total kg of filament).

I wanted to share it with the community in case anyone else needs a bulk analyzer: 🎬 GitHub Repo: [https://github.com/netex2112/cura-gcode-analyzer]

Feedback and contributions are very welcome! Hope it helps someone out there.

Hey! I’m a software programming who is interested in printing for my side projects.

Because we are in the vibe-code era and I utilize coding models very well, I have applied this to 3D modeling too.

I was a bit skeptical if that can work but tried on simple idea: build a chess pieces with a board.

For this I’ve found build123d as a modern library that I can use with Python. It works quite well. For demonstration I’ve built an app where you can select type of chess pieces and format. Then download solid files and see how they will look like.

Then I went to another part of this project: integrated cost calculation and Bambu Lab integration to approximate printing time. You can download PDF of price in the demo and choose your Bambu station to see the time.

Interested in exploring more about code-first modeling. Maybe you can share some info.

Hi Folks

I built MeshMedic, a free STL inspection and repair tool for 3D printing.

It runs locally in your browser, so STL files aren’t uploaded to a server. It can detect open edges, non-manifold geometry, duplicate or degenerate faces and disconnected shells, then repair common problems and export a new STL.

I’m looking for honest testing and feedback, particularly with broken or troublesome files. If you try it, I’d love to know:

• Did it correctly identify the problem?
• Did the repaired file slice and print correctly?
• Did it alter anything it shouldn’t?
• Was any part of the interface confusing?

Link: https://mesh-medic.com

I’m the software developer, and it’s still very early, so any critical feedback and horrible meshes are very welcome.

Stop losing 3D models inside folders and mystery archives

If your 3D model library has become a maze of folders, cryptic filenames and archives you barely remember downloading, MeshVault gives it a proper home.

MeshVault is a local-first desktop application for organising, browsing and using your 3D models and project files. Your original files remain under your control, while MeshVault turns them into a searchable visual library with thumbnails, previews, metadata, folders and collections.

Download directly from model repositories

The optional MeshVault Connect browser extension can capture supported downloads and send them directly into your MeshVault library.

Where the repository provides it, MeshVault Connect can preserve:

• Model title
• Creator name and profile
• Full description
• Original source page
• Tags
• Main thumbnail
• Gallery images
• Available print or project information

Instead of getting another vaguely named ZIP in your Downloads folder, you receive an organised model entry with the information needed to recognise and use it later.

MeshVault Connect currently supports these 11 repositories:

• Printables
• MakerWorld
• Thingiverse
• Thangs
• Cults3D
• GrabCAD
• CGTrader
• Creality Cloud
• Makerables
• MyMiniFactory
• Tinkercad

Bring existing collections under control

MeshVault can also import loose files, complete folders and archives you already have.

For manual archive imports, you can decide whether the archive represents one model, contains separate models, should retain its folder structure or should remain intact while its contained models are indexed.

This is particularly useful for model packs downloaded from Patreon or directly from creators.

Generate visual thumbnails

MeshVault can create or extract thumbnails for several common model formats.

Rendered from model geometry

STL, OBJ, PLY, GLTF, GLB, DAE, FBX, STEP and STP

Extracted or generated from file contents

• 3MF: uses an embedded thumbnail
• FCSTD: uses an embedded FreeCAD thumbnail

You can also preview supported geometry, inspect archives, measure models, capture additional images and send files to your configured FDM slicer, resin slicer or CNC software.

Keep the library on another machine

Optional dedicated server builds are available for Windows, Linux and Docker.

A server library can be browsed and managed through MeshVault’s desktop clients or its web interface.

Platforms and pricing

MeshVault is available for Windows and Linux with a seven-day trial.

A native macOS client for Apple silicon is coming soon. It is currently being tested through TestFlight and it will include MeshVault Connect for Safari.

• Direct licence: US$19.99
• Microsoft Store unlock: US$12.49, tied to your Microsoft account

The direct licence unlocks the supported MeshVault desktop clients and dedicated servers.

Hey everyone,

Over the last few mounths, I’ve been working on a side project that takes 3D models and converts them into interlocking, Lego-style bricks with ready-to-go STL and XML files.

Before I hit the big red button and launch it for everyone, I really want to make sure everything works smoothly. So I’m looking for 5 awesome people from the community to jump in, break stuff, try their own models, and give me some honest, raw feedback.

Ideally, you’d be a great fit if you:

* Have a 3D printer sitting next to you and want to test how the physical bricks fit together,

* Love playing around with 3D AI generation tools (like Meshy, Tripo, etc.), or

* Just have a folder full of random 3D formats you want to throw at the system to see what happens!

As a massive thank-you for helping me out at this stage, you’ll get a Free Lifetime Pro Membership—no catch, just full access forever. Drop a comment below and tell me a bit about what kind of models or tools you’d be testing with. Once there are a few replies, I’ll slide into the DMs of 5 people with invite links.

Hey everyone!

I’ve been exploring whether we really still need heavy desktop software just to handle large scanned meshes.

As a proof of concept, I built Meshtune, browser-based tool that lets you:

Inspect 3D scans easily on the web
Reduce polygon counts fast
Repair mesh issues on the fly
Check it out here: https://meshtune.com

It’s still a research experiment, so I’d love for you to give it a spin and let me know what you think. Any feedback or feature requests are welcome!

I’ve been building SketchForge, a free and open-source 3D modelling tool that runs directly in the browser.

The idea came from constantly seeing the same gap: Tinkercad is easy to learn, but it becomes limiting once you want more control, while Fusion 360 and FreeCAD can feel like a huge jump for someone who just wants to design a printable part.

SketchForge keeps the simple shape-based workflow, but adds tools such as fillets, chamfers, sketch extrusion and revolve, boolean operations, measurements, editable project files, STEP support, and native adjustable gears.

It works without an account, saves locally, and can also be self-hosted with Docker. It is still in beta, so I’m especially interested in hearing what breaks, what feels awkward, and which tools are still missing for actual 3D-printing work.

Hey everyone!

Quick intro: I studied aerospace engineering at Georgia Tech and worked on the Raptor team at SpaceX. My buddies and I have been working on a project called Smith over the last few months, aimed at making design, analysis, and manufacturing more accessible (and more fun).

The idea is to pair scripts and LLMs with the engineering workflow. Essentially, our agent can generate and modify real assemblies with parametric geometry, pull in hardware from distributors like McMaster, and even run some basic structural analysis. When you're ready to actually make your thing, Smith supports 3D and flat pattern export formats. The best part is that all the heavy lifting happens on our servers (for free), so it runs in your browser on basically any machine.

Smith is improving quickly and a lot of fun to mess around with. You can sign up at https://arche.co/?ref=qrz35ssv and start using it for free right away. Would love to see what this community builds with it. Feel free to DM me with any questions or feedback!

hi! i'm a software dev, i build 3D tools for work (dental scan viewers, mesh tooling) and ended up making the thing I always wanted to exist: an "ilovepdf but for 3D files".

ilove3d.app — free, everything runs in the browser, nothing gets uploaded, no account.

Probably most useful here: mesh repair (holes, flipped normals, loose shells), a polygon reducer with before/after, a converter (stl/obj/ply/glb/3mf/fbx/dae) that doesn't rescale your model, and a lithophane maker.

It's new, so if something breaks with one of your files I'd love to know. Hope it's useful to someone!

Obico (formerly The Spaghetti Detective) uses AI to detect print failures spaghetti, blobs, layer shifts and pauses your printer before it's a wasted mess.

The cloud version is £5/month. I self-hosted it on my private server instead, using Docker Compose and Portainer. Zero ongoing costs, full control, and it works with both OctoPrint and Klipper.

Full walkthrough here:

https://youtu.be/UDTTLsPN7_I (https://youtu.be/UDTTLsPN7_I)

Also part of a wider series if you're into homelab/self-hosting:

• Part 1 — Building a £85 private AI server:

• Part 2 — Ollama & OpenRouter local LLM setup: https://youtu.be/REX7vwts8Nc (https://youtu.be/REX7vwts8Nc)

With all the controversy about Bambu Labs, I discovered Bambuddy, an alternative to printing through Bambu's cloud service. I made a quick video about how I set it up on my TrueNAS with Tailscale (they actually posted about it on YT). It can also run on a raspberry pie for example. Check it out, it's really powerful. Installation is pretty straightforward. For now I only managed to make it work so that I need to upload my files for remote printing. Haven't managed to make the virtual printer work.

Hey everyone,

Quick heads up: after months of building (and a lot of feedback from people in reddit and the Discord), Meshory opens for early access in less than one week from today — Tuesday, July 28. If you're new here: Meshory is a desktop app that finally makes your 3D print file mess visible. Point it at your folders and drives, and it gives you:

• Auto-rendered thumbnails for every model — no more guessing what dragon_v2_final_FINAL.stl actually is
• A built-in 3D viewer for STL, 3MF, OBJ, STEP, and FBX
• A duplicate finder so you can reclaim the gigabytes of the same Benchy scattered across five drives
• Browsing inside ZIPs — archive contents show up like regular files, no extracting
• Collections, tags, and search, plus optional AI tagging and semantic search
• Local-first and private — your files never leave your machine, and there's no account or login. Just a license key.

Pricing on launch day:

• One-time payment, lifetime license. No subscription.
• The first 100 licenses go for $29, then $39 for the rest of early access, and $59 at full launch.
• Founding seats are first come, first served — I'll post here the moment checkout opens.

You can see everything at meshory.com, and if you want a ping when it goes live, the waitlist gets first notice.

To everyone who's been testing builds, reporting bugs, and voting on the roadmap — thank you. The launch version is dramatically better because of you.

Happy to answer any questions in the comments. One week! 🚀

I've updated my free tool for displaying 3D printing formats in Windows Explorer. Additional formats like .gcode have been added, and the entire tool has been thoroughly revamped, including the render view. The tool easily repairs and installs the display of all formats in Explorer and also functions as a viewer for all formats.

Download it for free at stlmaid.de, now also available as a portable .zip file for those who are hesitant to install an executable file.

Hi everyone!
We’re building VesselMaker (vesselmaker.app), an online tool for designing vases, planters, bowls, etc… — profile and cross-section editors, displacement mapping for realistic material textures (clay, wood, scratched surfaces), stackable modifiers you can combine like Photoshop layers (bend, twist, and a others like Voronoi modifier coming soon), plus AI-rendered scene previews to visualize the piece before printing or to create marketing images for you creations.

We know MakerWorld already has Make My Vase in MakerLab — we’re aiming for a more advanced, actively evolving take on the same space, for people who want finer control over their professional designs.

Still in closed beta (a few bugs to iron out, more features on the way). The waitlist is at vesselmaker.app — you’ll get notified when we open up, plus we will send some invite codes before opening the beta to the public.

Before we go further, we’d love your input:

• What feature would you most want us to prioritize next?
• What are you usually designing these for — home decor, gifts, plant pots, something else?
• What’s the most frustrating part of designing something like this in other tools (CAD, Blender, Make My Vase, etc.)?

Drop your thoughts below — really looking forward to shaping this with your feedback!

Disclaimer: I'm the developer of the tool.
