I needed a stubby screwdriver for a project and I almost bought one from a hardware store...Duh! I can print one! All you need are the 1/4" hex bits which most people already have.
All parts were printed on a TOM with a MK6+. My settings were: Object infill% 65, Layer height(mm) .27, Number of shells 0, feedrate (mm/s) 32.
Print the part and install a bit.
