Drill / Bit Attachment for DC Motor

Original model from @DaVinci2000, I'm making a mini electric drill/screwdriver and needed something like this that would fit on a DC motor shaft.



Print settings (copied from DaVinci2000):

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
