Portable allen wrench holder (1.5 - 6mm)

thingiverse

I was looking for a hex wrench holder for all sizes from 1.5 to 6mm with numbers printed in the surface. Unfortunately, printing tolerances are hard to predict, so if a hole is to tight, you could try to hold the wrech with spliers, heat it up over a lighter and then insert it in the hole (especially for the tiny ones).
