This is a version of my mini-screwdriver that now works with a double-sided ¼" bit. The bit needs to be 70mm or less in length.

I have included two Print Profiles (PETG settings):

1. Regular screwdriver with body that fits a double-sided bit
2. Screwdriver with a magnet embedded that fits a double-sided bit. ¼" x 1/16" or 2mm x 6mm magnets can be used. The print will pause so you can embed the magnet.

If you want to print in PLA, you'll need to use your own PLA settings.

Print Settings

1. Layer height - 0.15 or 0.1 (I have not tried 0.2). I think smaller layer heights will work better because of the small threads
2. 4-5 walls (or use 100% infill)
3. USE A BRIM - because they are so skinny and tall, it'll most likely fail with out a brim.
