Gridfinity Compatible Nesting Bin 1x1x(1u,3u,6u)

Its got everything you'd want except a lip! These bins can store in each other and are roughly the same size and shape as a 1x1 Gridfinity cell, and will fit baseplates AND can have magnets. What more could you want? 

I made this because I find myself using bins as very temporary sorting bins that then can be stored compactly, it would be nice to not waste cells on empty containers in waiting, maybe you feel the same.

Be careful removing them from the bed as those walls are pretty thin (on purpose)
