Stubby 1/4" bit screwdriver handle

thingiverse

Stubby screwdriver handle for 1/4" bits. This one has about a 10mm recess for the bit, so works well for shorter bits. I designed this at a 7.9mm hex (as measured in Fusion 360) and this fits the bit nice and tight for me. I'm using PETG as this will spend time in my tool box, I'm using a higher infill rate to allow for strength to keep the bit area from being rounded out. I print with the recess up, neither a brim nor supports were necessary.
