Printing one screwdriver is ~ 45g and 2 hours, the profile sums all the versions and makes it look heavy and slow.

A modular screwdriver handle designed to accept a drill adapter for standard 1/4" hex bits. The adapter is press-fit but should be glued for long-term strength. The rear compartment stores 15+ bits and closes with a threaded cap.

5 tolerance versions for the drill adapter are included (6.45, 6.50, 6.55, 6.60, 6.65 mm flat-to-flat). A separate test plate with labeled holes lets you quickly check which tolerance works best for your printer before committing to the full handle. And if you don't find anything that fits, let me know and I'll add more versions for your needs.
