Gridfinity Bin and Holder, these you can edit using FreeCAD. Fully customizable to your preferred size. It will work from 24mm width.
Use VarSet to change grid width and the number of blocks.
Extra blocks can be added in X and Y direction. If you want more than one block, just enter the new number instead of 1 (default value).
