so it is a simple screwdriver for keychain, uses ¼ inch bits or in millimeters 6.35(the standard bits for a drill) 

If the bits will not fit well use a bit diffrent scale 95-105% should do.

!!Supports are mandatory!!

Print settings:

Printer: Prusa mini+ 

Filament: Petg

Temp: 245 and 85

Supports: Custom/Printbed only will do

Also sorry for the bad pictures.
