Why these break
Selector pin knobs crack off the pin shaft. 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 PETG-CF. Carbon-fibre PETG is noticeably stiffer than the stock plastic, so the part holds its shape under clamping force instead of slowly creeping loose.
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.
