Work colleague has a major love for the XCub and wanted knobs to suit. Started with Stephen's Piper Arrow knobs and tweaked to suit.
We went through a few different iterations of the Prop and Throttle knobs.
I'm far from an expert with 3D modelling, but was able to use Tinkercad to come up with something good enough for now. Feel free to remix and refine!
Mixture Knob unchanged from Stephen's design
Prop Knob modified angle/sleeve location to sit a little higher
Throttle Knob and Extension modified for longer extension, different knob
Some supports needed. Use your best judgement (I only used supports to hold the sleeve up, and the base of the Throttle Knob ball. Support blocker inside the sleeves).
Resolution: 0.2
Infill: 15%
Supports: Some
Bed Adhesion: Skirt
