The hot/cold lever knob on the Oras Cubista is tiny and if not used frequently it is very har to turn therefore I designed a leaver knob to make the adjustment easier. The fit is a little tight but you should be able to slide it on for a snug fit. If your knob is already stuck make sure to loosen it before attaching the leaver - because of the momentum of the leaver it will potentially break the fitting when turning it if not loosened first.

0.4 Nozzle size and added print profiles for 0.12, 0.16 and 0.20 layer height.

25 % infill for strength

No support necessary - completely PlugNPlay

Printed in PETG for durability but PLA should work just as well
