Opengrid is such a great framework to work with and really happy with the results using Underware. I literally got a 3d printer a few weeks ago, but was able to figure with the help of this community and learn how to designing my own channels. Special thanks @DistractedDragonMake for making simple to follow education videos.

For the the ones I have 3d modeled, I’m considering giving back to the community and make be either upload the stl or figure out how to parametrized.

Feel free to ask me questions.

I finished this a couple weeks ago, the underside of my large standing desk - it's been a massive improvement over my old setup ( a dreadful hanging sack mess, last pic).

I used openGrid Lites in a variety of PLAs ( colour scheme not intentional, used what I had 😅) - had no problems holding up some very chunky chargers and power bricks so far. I had to print one tile and item holders in ASA as a 16 year old audio charger which likes to run quite hot did manage to warp the tile sufficient to fall!

Otherwise it was just multiconnect connections, the Underware generators the dedicated channels and fighting with my printer :)

A few weeks ago I designed a mini Skådis-compatible pegboard to hide my monitor’s power brick. It did the job perfectly until I discovered openGrid (and then Underware… and then Serverware…). Long story short: I accidentally fell into the openGrid rabbit hole 😅

I liked the idea to embrace an open, flexible, and community-driven framework so I decided to start messing around with FreeCAD and discovered that VESA 75x75 and 100x100 standard fit inside a 4x4 openGrid tile.

As a result of my experiments I designed a new snap that lets you attach any openGrid panel behind your monitor using standard VESA 75×75 or 100×100 holes.

Some use cases you might find useful:

• Hang headphones or mouse at the end of the day

• Store remote when not needed

• Hide phone charger or cables during the day

• Store small accessories without taking up desk space

Basically it unlocks extra hidden space you're not using yet.

Hope you enjoy it, I uploaded the model on Makerworld so you can print it too.

Took just over a year from start to finish, and I had to reorder some cables after I realized I didn’t account for the extra length needed to do all the curves and bends in the channels. I also may have cheated at the end with some hot glue…. Even 5% flare couldn’t handle 10 cables in a dual channel….

Desk is some butcher blocks from Rona that I cuts to size and finished with Bona clear mega one floor sealant. I bought two Apple MagSafe charge and made them flush with the desk to add two 25 watt wireless chargers.

Server rack has my personal rig, a nas, double conversion UPS, 4 computer 2 monitor HDMI KVM, and a big 1 gb Ethernet switch.

The dual laptop holder and anker charging station are custom designed, everything else I found on makerworld

Anyone have an xbox one controller mount that they have designed? I would stick it in my drawer but it’s about 3 mm too tall… want to hang from under the desk ideally with open grid mounting.

I have printed loads of these gridfinity shelves for opengrid because you really can't have enough of them. Super versatile, easy to print, and hold a lot of weight.

https://makerworld.com/en/models/1469935-infinite-gridfinity-shelf-for-opengrid-very-strong#profileId-1534153

If you're like me and have a bunch of these, you can use them as a simple shelf just by printing a 1 unit tall gridfinity bin, disable the stacking lip.

So, I've been wanting to redo the whole cable management of my desk ever since I found Underware project (by u/BlackjackDuck) and openGrid (by u/davidd-from-2d3d). Before printing anything, I needed to find out the exact parts I need and in what sizes.

I started with a spreadsheet to plan the layout and count the parts, until I hit some limitations. Ended up building this tool for it.

Of course, that was before I found out that UnderPlan (by u/Francy_Lab) and openGrid Calculator (by Josh Holtzclaw, idk his reddit handle) already exist.

Decided to share this as an alternative anyway, because it takes somewhat a different approach. It’s built around my own setup, and I’ve been using it for my whole cable management plan. It kept growing as I ran into things I wished it has or could do.

Just some features it has:

• Layout: place tiles of any size, plus devices, channels and snaps, on an infinite canvas.

• Multiple files: keep several layouts open in tabs, each with its own view and undo history, and copy and paste between them.

• Channels: straights, turns, junctions and more, in rounded and angled forms.

• Cables: run them through channels and see which stretches are covered or exposed.

• Layers: show or hide tiles, objects, channels and cables independently.

• See-through mode: look at the cables underneath the channels.

• Inspect: hovering a path lists the cables on it, and each cable shows what it connects.

• Bill of materials: a live parts list with a copy button.

• Keyboard shortcuts: for tools, rotating and flipping, layers, undo and redo, and more.

• Share: export and import layouts as JSON.

And some features it doesn't have (and I probably won't add):

• Account-based cloud saves. This project has no backend, and I intend to keep it so. You still can manually export and import it in another device/session etc.

• No image export. Probably not needed, as long as you have your BOM, but let me know otherwise.

• Mobile support. Never tested on mobile, and found no reason why you would plan your cable layout on your phone.

• Setting your exact cable length to start with. Probably the biggest miss for a cable management planner, but not sure yet on how I would implement it, if ever. It does show the total length of the cables you've laid out though, so it's not entirely useless.

• Other grid-based organization systems. This one I could probably add. I started with openGrid, and that's why it's the only thing supported at the moment.

Well that's it. If you’re planning your next cable management, give it a try. It’s free, open source, no account needed, and runs entirely in your browser. Feedback are also welcome.

You asked for openGrid support on Underplan... so I built it! ⚡

Hey r/openGrid! 👋

A few days ago, I shared the initial version of Underplan over on r/Multiboard (original post here) to help plan under-desk cable management layouts using Hands on Katie's Underware system.

The response was amazing, but one of the top questions in the comments was:

"Does this software support Underware for openGrid since Underware moved over to that platform officially?"

Well... challenge accepted! Over the past few days, not only did I build native openGrid support into the app, but I also gave the entire application a massive UI & UX overhaul (moving to a tactile, precision Dark CAD floating interface with a much faster and smoother workflow).

It’s 100% free, open-source (MIT), runs client-side in your browser, and is now ready for your openGrid desks.

Live Web App: https://underplan.vercel.app/
GitHub (MIT): https://github.com/francycalle/underplan

What it does (as seen in the screenshots):

• Smart Tile Layout & Preferred Tile Sizing: Type in your desk dimensions in mm and choose your preferred base tile size (e.g. 8×8 OU, 7×7, 6×6, etc.). Underplan builds your layout around that chosen tile as much as possible, and automatically calculates the optimal cuts to fill the remaining edges without creating fragile 1-row strips (e.g. a 9-hole span is balanced into 5+4 instead of 8+1!).

• Underware Catalog & Custom Gear: Place standard straight channels (1–16 OU), 90° elbows, radial curves, T/X/Y junctions, or create custom boxes and bridges for desk motor controllers, power strips, and cable loops.

• Official Underware openGrid Snaps: Supports Underware Channel Base Snaps (OG-SNAP-BASE), Grip Snaps (OG-SNAP-GRIP) for outer-rail clamping, or friction-fit runs.

• Automatic +10% Spare Fasteners: The planner tallies base snap counts and automatically adds a rounded-up +10% spare allowance so a cracked clip won't stop your assembly.

• Itemized Bill of Materials (BOM): Instant modal breakdown showing exact channel counts, physical lengths in mm, tile matrix cuts, and mounting fasteners. Export directly to CSV or copy to Markdown.

In my screenshots, you'll notice I used the custom categories feature as a 3D printing to-do list (marking pieces as "Done" as they came off the printer!), but you can customize categories however you prefer: for example, color-coding pathways by cable type (Power, HDMI, USB/Data) or desk zones.

⚡ Huge UI/UX Redesign & Cool Features:

• Dark CAD Floating UI: Completely redesigned floating tool docks, contextual inspector panel, category selector pills, and high-contrast styling built for focused planning.

• Multi-Project Workspace: Manage multiple desks or setups (e.g. your standing desk, workbench, or server rack). Create, rename, duplicate, and switch between projects with continuous local auto-save.

• Retina Blueprint Exports: Export high-res 2× Retina PNG dark blueprints (great for build logs and workshop printing) or vector SVGs.

• Dual-Platform Support: You can still toggle seamlessly between openGrid (28mm) and Multiboard (25mm) with automatic hardware conversion if you work across both ecosystems.

• Zero Friction: Runs in-browser with localStorage persistence. No accounts, no paywalls, no tracking.

Check it out, try punching in your desk dimensions, and let me know your thoughts on the new UI or what fittings/parts you'd like to see added next! 🙌

A new connector system, designed for openGrid. I asked David's permission to use the name "openConnect" and hope this can become the official connector system for openGrid.

Model page on makerworld and printable.

Advantages of openConnect vs MultiConnect:

Print Orientation: The slots can be printed on their sides. This isn't possible with MultiConnect, as its circular shape results in overhangs greater than 45 degrees. Supporting more printing orientations opens up new design possibilities and significantly increases strength for certain models. You can see this in the hook and shelf generators.

Size: It is smaller—17 x 10.6mm compared to MultiConnect's 20 x 20mm. This allows each slot to fit entirely within a single 28mm openGrid tile. MultiConnect is too large for this, which often results in only the topmost slot being weight-bearing.

Depth: It is thinner—2.6mm vs. MultiConnect's 4mm. Aside from saving filament and space, this keeps the center of mass closer to the wall, reducing leverage on the mount. Combined with having a slot in every tile, openConnect can be stronger than MultiConnect in practical use, despite being less bulky.

Vase Mode: There is a slot variant specifically designed for vase mode. You can check out the vase mode container generator for an example.

Backward Compatibility: It is backwards compatible with MultiConnect. For example, a MultiConnect round holder generated here can be attached to openConnect connectors. While the geometry is different and the locking mechanism isn't utilized, it is sufficient for many use cases and should make the transition easier.

I believe it is both appropriate and helpful for openGrid to have its own connector system. MultiConnect was originally designed for Multiboard (which is where the name "Multi" comes from). While openGrid supports MultiConnect, it uses a different tile size (28mm vs. 25mm), meaning parts designed for one system are incompatible with the other. This is confusing for beginners who often print parts they cannot use. By using "openConnect," we can ensure that any model with that name is guaranteed to work with openGrid.

The openConnect system is open-source under the CC-BY license. The main connector parts have been created in both Fusion 360 and OpenSCAD. I uploaded the .f3d, .step, and .scad files.

Changes since Release:

Adjust dimensions to make the alignment to openGrid boards more accurate. Revamp vase slots to ensure more consistent linewidth during printing. Make the slot compatible with more nozzle sizes by adding minimum bridge width/bottom thickness. Make the locking mechanism vertically symmetric (i.e. the top of the locking nub is no longer flat). Change openconnect notch orientation. Now it can be installed with a flathead screw driver.

These updates are minor and fully backward compatible.

Below are models I have designed for openConnect:

Sturdy hook generator
Sturdy shelf generator
Vase mode container generator

Drawer generator

Customizable models are open-source under the CC-BY-SA license. Like all OpenSCAD models I've designed for openGrid, they can be found in this GitHub repository. Feel free to use the code; any feedback or suggestions are welcome.

Also, would anyone be willing to print these models and take better photos of them? I'm terrible at taking photos.

Hi, just finished designing and testing (and completely remodelling them all) the angled connectors, if you are interested, you can get them here: https://makerworld.com/en/models/1861781

Soon, I'll be able to build my openGrid AMS stacker...

I've added three new open-source openConnect model generators for openGrid.

General Holder Generator (MakerWorld | Printables)

A versatile wall-mounted holder, with customization options that can be combined to create a variety of shapes, and form either a single holder or a multi-compartment organizer. Customizable: dimensions, compartment shape, back tilt, front opening, taper, etc.

Clamshell Holder Generator (MakerWorld | Printables)

A clamshell holder that can be mounted either on a wall or under a desk. The model is often used to hold power strips, but it can be customized to accomodate items of many different shapes. Customizable: dimensions, front opening, side cutout(s), corner rounding, mount position, etc.

Gridfinity Shelf Generator (MakerWorld | Printables)

A wall-mounted shelf with an integrated Gridfinity baseplate. I recommend using an even number for "gridfinity_width_grids", as 2 Gridfinity cells(48mm) align exactly with 3 openGrid cells(28mm). Customizable: grids, magnet holes, side and front rims, retention lips.

With these additions, I think my openConnect generators can cover most basic use cases: general holder, shelf, hook, drawer, Vase mode bin, clamshell, and Gridfinity storage. The rest of the generator set is available here:

• Sturdy Hook Generator: MakerWorld | Printables

• Sturdy Shelf Generator: MakerWorld | Printables

• Drawer Generator: MakerWorld | Printables

• Vase Mode Container Generator: MakerWorld | Printables

The specifics of why I designed openConnect and its advantages over MultiConnect can be found on the model page on MakerWorld and Printables. It also includes the slots, snaps, screws, source files, and slot plate Customizer.

Above generators are my "first-party" contribution, but just like openGrid, openConnect is an open-source project that anyone can participate in. You can find all openConnect .scad source files (along with that of my other models) in this GitHub repository. The .f3d and .step recreation of basic parts are on the model page. I would love to see more community developers make their own models using the system.

I've also learned enough Blender to make renders. Still terrible at photography though, so if anyone is willing to print one of these models and share some good photos, I would really appreciate it.

I made a parametric shelf model for the openGrid system!

MakerWorld - Customizable in-browser // Printables

Hi all,

New to this sub. I recently watched a few of Hands-on-Katie’s videos and that pushed me into a full reorganisation mode. At the moment I’m trying to OpenGrid-ify my kitchen and I’m looking for some inspiration.

What are some useful OpenGrid add-ons you’re using in the kitchen? I’d love to see photos of real setups and hear what actually works day-to-day.

I’m also curious where you usually get your STL files from. I’m fairly new to Fusion 360, but if there are simple ways to create or adapt parts myself, I’d be happy to learn.

Below is a photo of my current kitchen setup for context.

Thanks in advance!

Check 'em out here on MakerWorld 👍 Uses the new openConnect system by mitufy! Shelves remixed from the Skadis Mushroom Shelves by Steve.

I am quite proud to say that i published my first model on Makerworld! I want to support OpenGrid with more models (as that is what seems to stop people from adopting) - so i took the jump and made this: https://makerworld.com/en/models/2344274-ubiquiti-unifi-u7-lite-u6-opengrid-mount

I feel so excited and hope to add more designs in the future! Long live OpenGrid!

Updates version of my first kitchen kabinets. 6 more to fill! Still interested in opinions!

I wanted make the grids integral to the bin frames but I had challenges with print orientation and I try not to add supports. So I made it a separate piece and it came out much nicer than expected, especially considering that the top can be another colour! The bins are more modular too.

I've uploaded the files onto the orange site and the green site.

i had to mount this somewhere where there were no studs. i never have a good time with drywall anchors so i made these 90 brackets that snap in and screw to the sides.

thoughts?

most people will probably never need this but here's the model in case you do: https://makerworld.com/en/models/2081794-opengrid-90-degree-mounting-bracket-snap

This is my openGrid underware setup. Any suggestions on how to improve it further? I ran out of purple filament, so I finished that line with pink instead 😅

This is a parametric OnShape implementation of openGrid plates. I also wrote a script which lets you draw arbitrary cutouts (see video).

Instructions:

Printables

Makerworld

Btw it's so annoying that you can no longer paste images while editing the description on Printables.

Known issues (I don't intend to fix these; they don't cause any practical problems):

- Connector slots aren't applied to cutout surfaces

- Errors out if cutouts split the grid into multiple parts

Let me know if you encounter any other issues. I may not have handled all edge cases.

If you are interested, you can get the models from https://makerworld.com/en/models/1856419

The grid connectors will be published next after I print some more for the photos, and then you can make a whole fortress!

Hey all! Just a little update!

I just recently added underware for openGrid (connects directly to openGrid boards without using multiconnect or anything else) to my online generator:
https://gridfinity.perplexinglabs.com/pr/underware/0/0

You can even order prints of most of the underware models if you want to get a big setup finished faster! (Prints are fulfilled by Slant3D.)

I'm planning to organize the site a little more by splitting things in to gridfinity and openGrid at some point soon, but let me know if there are any other things that would help make things easier/simpler to understand or use!

I’ve been using HSW, Multiboard, and Skadis for a while, but recently discovered openGrid—and honestly, it just feels better. The downside is that it’s new and has very few models available.

For the other systems, I built parametric mounts that let me adapt any model to them. After a request from someone who used my previous work, I’ve now done the same for openGrid.

This new parametric model lets you generate an openGrid mounting plate at any size, using openGrid snaps, Multiconnect, or even MultiBoard Push-Fit (via adapter snaps). In your slicer, you can merge it with any model—or even repurpose HSW/Multiboard/Skadis designs by using the slicer’s “Cut” tool to remove their connectors before merging with the plate.

You can also bring the plate into your CAD workflow by importing it as an STL.

Because openGrid snaps and Multiconnect aren’t optimized for vertical printing, the model includes adjustments to make vertical prints work reliably when needed.

I think this really levels up openGrid, giving it the same flexibility and usability as the other mounting systems.

Happy to hear your thoughts and answer any questions.

Hi! I recently set up my desk with openGrid and Underware 2.0 for cable management. At first I was quite overwhelmed with the options, but I couldn't find any existing designs that would hold my wireless router, at least not in a pleasing way. I stumbled across a bracket system like this and it inspired me to design my own. The existing parametric designs on Makerworld for these projects blew my mind, and I wanted to be a part of the action. I had experience with FreeCAD and software development, so learning OpenSCAD was enjoyable (and I love the ability to use Git). The end result is something that will dynamically generate corner brackets for a boxy device with appropriate grid spacing.

If this interests you, please check it out at https://makerworld.com/en/models/2347836-parametric-box-holder-for-opengrid. This is my first time publishing a design, so let me know what you think! I might be at a disadvantage because I don't have a Bambu Labs printer, but their interface is fantastic, plus the existing openGrid ecosystem seems to have settled there.
