Small parts stacking containers no supports

Update 3/30/25:  By request I added another size: medium which is 77mmx52mmx30mm.

Update 3/26/25:  Added a profile that has a lid for the top box.  The lid is a tight fit but it has two little lips on both long ends to be able to pry it off easier.

These small stacking containers are great for sorting small parts like screws.  They connect together with a tight fit.

Each bin measures approximately: 77mm x 52mm x 20mm.
