Why these break
Throttle and shift knobs split on the lever. The factory part is made from styrene-based plastic that loses its plasticisers over the years. It gets glassy, then one warm day it lets go under a load it used to handle easily.
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.
As with everything in our library: whether a part can be reproduced depends on size, load, heat, material, and having a decent sample to work from. Send photos first — the assessment costs you nothing, and we'll tell you honestly if a genuine spare is the better option.
