Gene Cafe Coffee Roaster Knob

thingiverse

NOTE: Print as laid out in STL. Knob is designed to not need support. This is a replacement knob for the Gene Cafe Coffee Roaster. while I printed this in TPU and it’s an easy fit. Any filament should do but may need some tweaking. The top of the knob has a recess so the colored trim in the original knob, which is easily pried out, should fit with a bit of handwork. The knob STL posted differs slightly from the one pictured in that I slightly domed the top for aesthetic reasons. To get a really good color match Overland Space Gray PETG comes close to original knob color. I would have used that but am out so just printed, at 100% infill, with what my printer had loaded.
