Had a lot of 4mm HEX bits and wanted to make dedicated screwdrivers for my most used sizes. Mainly using for my FPV quadcopter projects.
You can print them in different colors and quickly find the bit size you need that way. Basically I mostly need 2mm hex, Philips head and a small flat end.
Those are two parts. The main holder part and the rotating end with a pressed-in 8x3 magnet. That way it's comfortable to use and you can stick them to some metal piece in your workbench and find them easily.
The rotating parts is held in place by a DIN912 M3 screw with a little super glue, so it can't unscrew. When screwed together you press fit the magnet in the hole and you're done.
EDIT: Sorry. I uploaded the wrong STL files. Corrected now
