Gridfinity Bearing Storage Bin

I found a few bins for storing 608 bearings, the best being this one. But the stackable model was 6U high, and had a full 9mm of floor below the grooves, which is a waste of space and plastic. I reimplemented the bin using Akio's parametric bin design, and used just 2mm of floor space to create a 5U stackable version.

Updated 2023-03-08: made the walls thicker and added a small lip around the slots. This should make the model sturdier, and hopefully keep the semi-circles from showing through the outer walls so much (or outright damaging them).
