Gridfinity rebuild IKEA Alex (36cm wide, grid 7x12) + Spacer

This is a gridfinity baseplate for IKEA Alex e.g. with article number 594.222.20, 004.735.46 or 904.861.39 width a total width of 36cm and a drawer width of 30cm.

The baseplate parts were generated with the scad files from https://github.com/kennetek/gridfinity-rebuilt-openscad.

I created a spacer so that the 7x12 baseplate fits tight in the drawer (y-axis).  There's still some space in the width (2-3mm) but this is ok for me. The screws for the drawer rails interfere with the bins.
