Tevo Tarantula Control Knob

thingiverse

I am creating parts for my Tevo Tarantula in purple so that it can have a striking purple/black theme going on. To achieve this, I needed a purple knob, and thus, I made one. Or rather, I designed two versions of the knob. The first version features straight sides with a hollow interior like the original knob, including a slight indent on top. In contrast, the second version is tapered, similar to the original, but it's filled in instead, boasting a flat top. The second version still has the wall thickness set at 0.5mm (from the first version), allowing you to see a ring around the knob where the hollow portion and solid portions meet. Thicker walls should prevent this effect, but I like the way it looks - reminiscent of a top hat - so I've decided to keep it. Printer Settings: * Printer: Tevo Tarantula * Rafts: No * Supports: No * Resolution: 0.2mm * Infill: 20% * Notes: Both versions need to be printed upside down to eliminate the need for support material. The second version requires no support material at all, but the first version may benefit from it. Post-Printing: The first version will require a slight drilling out to 15/64" to fit properly onto the shaft of the potentiometer. I recommend starting with a drill bit of 7/32" before progressing to 15/64". The second version, on the other hand, is a perfect press fit.
