Another rotary knob for heavy machinery. This one is created for an professional dish washing machine in a bakery.
It consists of two parts that can either be printed with a dual extruder machine or printed separately and glued together, as I have done.
The black knob is ABS, the white insert is PLA, because I don't have white PLA. Anyway, they glue together nicely using transparent two-component epoxy glue.
I included the SCAD files for you to adapt and use. Let me know what you made ;-))
