Suggest printing at .12mm layer height on a .4 nozzle, it should not require supports, but if you are having trouble printing it you can enable them, I suggest printing with the “Tighten” logo faced down.
The specs for the piece are as follows:
- Screw:
- Size: M7 (I've included only the thread in a separate plate if you want to do a test print before committing to printing the whole model)
- TPI: 20 (important, if the TPI does not match with your fan screw, it will start screwing but get stuck mid-way)
- Thread depth: 11.9mm
- Thread start offset: 3.5mm
- Thread starts: 1
- Knob:
- Height: 26.848 mm
- Diameter: 73mm
