This is a from-the-ground-up reimplementation of Zack Freedman's Gridfinity basic baseplates using CadQuery instead of Fusion 360. See this video for further information about the project:

This version is customizable in CadQuery so you can generate custom size baseplates, including ridiculously large ones like 10x10 grids etc. I have included a random selection of grid sizes from 1x1 up to 10x10.
 

#adjust these two variables to change the number of grid positions
x_grid_number = 3 #CHANGEME!
y_grid_number = 3 #CHANGEME!

I re-implemented this because it seems like a perfect fit for an open source CAD software like CadQuery. With that in mind I have also released the source code python script that was used to generate the STLs. I would love for others to help me create new organizer bins and/or re-implement organizer bins in open source CAD software like CadQuery or OpenSCAD.

I used CadQuery/CQ-Editor to design this with a recent version checked out from github on April 13th, 2022. Unfortunately CadHub.xyz does not have a recent enough version of CadQuery to render this properly (n.b. the issue is with lack of a combine argument in the older version of the eachpoint method).

CQ-Editor is available on github at CadQuery/CQ-editor, but the latest stable release will NOT run the included cadquery source code, so please instead use a static build from here: https://github.com/jdegenstein/jmwright-CQ-Editor/releases/
