Gridfinity Canon RF Lens Bin (16mm and 50mm)

I didn't see any lens bins for gridfinity for these smaller Canon RF lenses so I modeled simple 2x2 bin for them. It's designed for and tested with the Canon RF 16mm F2.8 STM and RF 50mm f/1.8 STM lenses, but it should work for any lens with that is roughly ⌀ 69 mm.
