A replacement knob for the UltiController. It's larger then the default one for more hardcore printing action.
Useful if you broke the origonal knob, or never got one. (If you broke into the Ultimaker HQ, and stole UltiController electronics, for example)
Print at 0.1mm layers, and put it on your UltiController. Then enjoy our extra sized UltiKnob!
For other knobs, adjust the SCAD file, but be warned, generating the STL from SCAD takes a while.
