Ergonomic Hex Screwdriver Bit Handle

This is my attempt at making a useful little handle for 1/4" hex bit inserts. It's designed for the "three-fingered" way you typically use these in tight places. You can apply down force with your index finger while spinning it with your thumb and middle finger. The large end is wide enough for you to apply some decent torque if you need to. I would encourage you to use PETG filament when making these.
