A 1x3 Gridfinity Bin inspired by the radius gauge pieces made by Beck. Modified to be stackable and fit in the gridfinity layout. 

You will need to superglue the base plate on top of one of the covers. I have alternate covers for both covers depending on which one you want on top. The alternate covers are designed to be more aligned with the standard gridfinity base plate. The normal covers have a chamfer to add some uniqueness. 

I tried to print out the base plate already attached to a cover but it kept failing so I removed it.
