20 Sided Die Shift Knob - 5 speed

thingiverse

I am working on designing an innovative icosahedron shift knob for a five-speed manual transmission. To ensure universal appeal, the base of this design is kept plain with only a centered pilot hole to make mounting adaptable across different models. How you attach it will largely depend on the specifics of your vehicle's make and model. A good starting point could be to use a high-density material in the printing process.
