Stessco Throttle Knob
Salt, sun and vibration are brutal on Stessco plastics, and the throttle knob usually gives up first. A tougher printed replacement breaks that cycle. We've made this style of part before and can usually print yours without drama.

Why these break
Throttle and shift knobs split on the lever. UV exposure breaks down the polymer chains in the original material. By the time the surface looks chalky or faded, the strength underneath is already gone.
How we reproduce them
This is a quick job on our end — we take dimensions from your old part, adjust for print tolerances, and run a small batch so you have spares for next time.
We print these in ASA. ASA is the UV-stable cousin of ABS — it holds its colour and strength through years of Australian sun where the original plastic went chalky and brittle.
Many plastic parts can be recreated, repaired, redesigned, or printed, depending on size, load, heat, material, and available samples. Bring in the damaged part or upload photos for assessment and we'll give you a straight answer before any work starts.
