Description

Left-thightening fan blade lock knob. My fan had a failing lock knob that came loose and decided to model a replacement one. Printed in PLA+.

 

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
