There are three knob designs to choose from. The smaller knob is low profile and shows all the heat options. The medium knob replicates the design of the smaller knob but increases the size for ergonomics. The large knob is easier to grip but only shows the heat level selected.
DO NOT print in PLA. Heat from the slow cooker conducted to the knob at high settings. PLA will get soft and degrade. Use a higher temperature filament like ABS, ASA, Nylon or PTEG. I personally use PETG.
