Gridfinity baseplate for KALLAX drawer insert

A baseplate to fit the drawer insert of the KALLAX system.There is a Gridfinity baseplate for this drawer insert already on Makerworld, but it uses 0.5 width boxes that I don't find very useful. This baseplate gives you a nice 6x7 grid of full squares, with built-in spacers.The KALLAX drawers are not exactly square, so expect a bit of a snug fit.
