Hex Bit Holder

thingiverse

I bought a bunch of 100mm Security Torx bits to use with my hex quick release tools, but found that they came without any holder. The hex quick release is a lot longer than those bits that are just hex alone, hence this is quite a deep holder. I whipped this up in FreeCAD and printed using TPU. The TPU allowed it to move and flex, and provides a nice tight fit for the hex end of the bits so that they do not come free unless you pull them out yourself. I don't see any reason why it wouldn't also work in other filaments - like PLA or PETG - but they won't provide any flexibility of course.
