This otherwise very nice and high quality looking bit set comes with horribly weak and brittle insert. It was already broken when I first opened it.

These sets are all almost identical, so I took the model I found here on printables and made it to suit my needs. 2x6 magnets will hold the bits in any position.

Optimised for printing with 1 perimeter, 0 bottom and 2 top layers, 10% infill.

Add modifier with more perimeters around the hanging holes if you are going to use them.

BTW the holes completely accidentaly fit the HSW spacing ;)
