This is similar to other parametric models, but this is OpenSCAD based.

Turns out its hard to fit a grid of a different dimension inside another grid of a different dimension reliably without relative alignment. But it's been done, so here you go.

This is a gridfinity 1x2 with 2x3 tray routes for six total trays.

There is also a lid that can be printed should you want to keep your parts contained and separated.

If I find a bigger use for this I will fix the code to be properly parametric. It has been done.
