Rugged Box for Step-Drills (4-12 / 4-20 / 4-32)

I loved @Christian's model , but it didn't work for my set. It is a cheap set with 4-12mm, 4-20mm and 4-32mm bits. I don't know how to design, but Tinkercad saved the day. You can print the “ALL” file or each model (2 latch). You'll need 6 M3 x 20 screws.
