Sekru Draiver

ratchet and non ratchet screwdriver. just looks like the ltt screwdriver. for ratchet, i use ratchet from cheap aliexpress ratchet screwdriver. this cheap ratchet work no problem, but the bit holder is a bit flimsy, since the mechanism is push to open and close the bit holder, when tightening or loosening a screw, I always accidentally pressed it.

BOM:

1. Cheap ratchet (Just take the ratchet) ==> aliexpress
2. Bit extender ==> aliexpress
3. m3x6mm heatset insert
4. m3x8/10 screw
5. locktite blue
6. bearing with 14mm OD, 8mm ID, and 4mm length I use MR148ZZ (Remix it your own if you use different bearing)

TODO:

1. Add magnetic version of bit holder

NOTE: For the bit holder mechanism, I use the same mechanism as Erer2001 screw driver design => https://www.printables.com/model/580045-not-ltt-screwdriver-fancy
