3D Printed Screwdriver (no magnets required!)

3D printed screwdriver with a 3D printed locking mechanism.

Yes It would be easier to go out and purchase a swappable bit screwdriver. But the manufactureres seem to think that I need to fit 800 other bits into the handle so the handles alwasy feel oversized to me.

I needed a light duty screwdriver for makerspace work and general screwdriving needs. In the tests I have conducted with this tool, it can unscrew most bolts provided they are not stuck, I have also driven a coarse thread screw into a wooden board partway to start it for my drill. It works well for the materials it is made out of. Mine is PLA but PETG would work much better due to its higher layer adhesion.

All parts are swappable if something breaks and a "handle blank" file is included for those who wish to design their own handle.

!!!IMPORTANT!!! This design will only function correctly with impact driver bits. The magnetless locking mechanism needs to use the notch from the impact bits in order to function properly.

Materials: 1x M3x20mm flat screw 1x M3x16mm flat screw 1x M4x50 socket screw 2x M3 hex nut 1x M4 hex nut

Assembly: You will need one of each part that ends with "f". The handle blank is not required but if you would like to customize a handle you are more than welcome to. (I wanna see some meme handles.)

Please check the assembly file for where the hardware goes. The M3x20 attaches the latch to the shaft, the M3x16 attaches the switch to the shaft, and the M4x50 attaches the handle to the shaft.
