IKEA UPPHETTA knob with threads

Because my IKEA UPPHETTA knob broke I decided to design a new one instead of using one of the already existing designs because I wanted it to have a nice fitting thread so I can just screw it on the metal rod.

There is no need of gluing it onto the rod.

I prited this thing with a resolution of 0.15 but 0.20 should be enough.
