A compact, foldable bit box that is printed in one piece and snaps closed when in the folded state.
If your printer can print 0.2mm tolerances this should be an easy print! If not, i would recommend you to adjust horizontal hole expansion in your slicer to create bigger distances between the perimeters.
Prints easily in under one hour or even much faster!
I've already used these many times and they are doing perfectly fine so far.
