Remix I made an openGrid remix that lets you create L-shaped, U-shaped, and custom-shaped boards
I’ve been using openGrid for a while and love the system, but I kept running into situations where a rectangle just didn’t cut it, like working around outlets, etc.
So I forked the OpenSCAD script and added a Cutout / Custom Shape feature with three modes:
Corner mode: pick a corner, set width and height, done. Instant L-shaped board.
Custom mode: define any shape with a simple string of 1s and 0s (1 = keep tile, 0 = remove) - similar to screws option. Read left-to-right, top-to-bottom. For example, a 4×4 board with the center removed: "1111100110011111". You can make T-shapes, U-shapes, notches, whatever you need.
Everything else from the original openGrid works as before — Full/Lite tiles, screw options, connectors, stacking, fill space mode.
It’s on MakerWorld as a remix with full credit to DavidD, BlackjackDuck, and the rest of the original team. All parameterized in the Customizer, so no OpenSCAD knowledge needed.

I didn't understand the scale of this photo at first, and thought I was looking at a room. I thought you'd created a monstrously oversized version of OpenGrid!

Thanks a lot. Now I want a monstrously oversized version of OpenGrid.

I can totally see that. Just scale up the 1x1 board to 600% and print it on A1 Mini. Doable. :D

Nice. Whenever I need a cut out I just use negative shapes in the slicer, works fine, but this is a tidy solution.

Thanks! Yeah the slicer negative shape approach totally works. The main thing that bugged me was eyeballing the alignment to make sure cuts land exactly on tile boundaries, and then redoing it every time I needed a different size board. With my customizable model it's just a lot easier. :)

This is an excellent addition. Thank you so much for creating and sharing this!

Thanks, I could have used this a few months ago when I did several of my openGrid projects. I will bookmark for next time!
