This is a model of a round knob to ajust the temperatur inside a caravan. The original broke so i designed one. My source of inspiration: https://www.camperflash.it/de/home/kessel-und-ofen/ersatzteile-fur-kessel-und-herd/trumatic-thermostat-bedienknopf-3d-graue-reproduktion.5.1.84.gp.82459.uw

Just use the NumberFile in your Slicer to cut from the original form. (Or take the one where i allready cut it out) One color workes fine but you can add a colourchange for the 3rd Layer.
