When you use the Raaco storage boxes for small quantaties of small parts the smallest (A9) insert containers prove to be too large sometimes. I designed these 'half' A9 containers so I can organize my small parts better.
I added an stl with 2 containers and an stl with 1. i recommend to always print an even number because they are used in sets of 2.
I sliced it with simplify 3D and set it up so it prints the wall with only perimeters. This avoids a lot of shaking.
What I did to get that was:
Nozzle: 0.4 mm
Extrusion width 0.4
allow infill overlap 20%
