This is a remix on Varzaman's design: https://makerworld.com/en/models/192163-gridfinity-12-ruler-bin?from=search#profileId-212291

I just added a slot so the two parts would interlock and the whole bin would be more stable without the need for glue.

The single ruler bin is ½ unit wide and the dual ruler bin is 1 unit wide.
