Ever since I saw a titanium screwdriver I wanted one, (don't know why, they are so expensive,) I was inspired by this, https://urbanedcsupply.com/products/rain-z-hex-bit-screwdriver-anodized-titanium.

But I am a maker with a 3d printer and parts, so I decided to make one.

This is the ULTIMATE SCREWDRIVER, and without hex bits in it, it measures almost 91mm in length. The end cap is a fidget/ stand/ easy palm rest, and houses a 608 bearing. I designed the cap to fit loosely around a bearing and be screwed down with a retaining screw. And the fit for the bearing on the drive shaft is very tight but can still be pulled off if needed.

So, the nitty gritty, you will need to print the driver with supports and make sure that it is very attached to the build surface, a brim that set at zero with nine outlines couldn't hurt. The cap and retaining screw can be printed without.

The only parts you will need to provide are a 608 bearing and a 1/4-Inch Socket Drill Bit Holder, I made this a requirement because a plastic hex bit holder would be too soft for the torque that I put on screws, also I like the weight that it gives the screwdriver. In the future I can put up a non-needed 1/4 bit holder for main body.

For now happy printing makers!!!

EDIT!

This is for those who do not want to use a socket bit or do not have one. I added a fully printable new driver shaft that can hold just hex bits, I also made room for a magnet to be placed in the driver as well it is for a 3mm by 2mm magnet. This new model does not require any supports to be printed, however, I do recommend adding a very large brim to help with adhesion. The full print is also slightly shorter.
