Universal handle for drills from 1.5 to 6 mm as well as screwdriver bits.

The designs available on Thingiverse either fit just single drill size or require printing a set of sockets for each drill size. I needed all-in-one adjustable handle. After a few ideas and iterations I ended up with this simple design.

Don't over tight the nut as it may crack along layers. It's not meant to keep drill as firmly as regular metal drill collet.

Updates:

• v1.4 shortened nut, so that it does not stick out too far for bigger drill sizes

Print settings:

• Filament: PETG, ABS, alternatively PLA, for arms I'd recommend even HIPS as it contains rubber and drill won't slip that much
• Layer Height:0.2
• Line Width:0.45
• Wall Line Count: 2 (handle) and 3 (nut & arms)
• Top/Bottom Layers: 3
• Infill: 20%
• Fill Gaps Between Walls:Nowhere
• Cooling:50-100%
• Print speed: up to 50 mm/s
