A handle for 4mm hexagonal screwdriver bits. The tiny bits needed for replacing resin printer foils. Also included is a handle for the more common 6mm bits.

Print vertically, with the handle facing down. It needs some support. Give it plenty of wall thickness and a high, say 30%, infill for strength. You may need to adjust the x-y hole compensation depending on the filament and printing settings. I used 0.3 mm for a tight fit.

I only tried it with PLA.
