Why these break
Lock knob splits at the rod socket. Heat cycling is the killer here: years of expanding and contracting work-hardens the plastic until a routine bump becomes the final straw.
How we reproduce them
Reproducing one is straightforward for us: we measure your sample (broken is fine, as long as most of it is there), match the profile, and print in a tougher modern material. Turnaround is usually within the week.
We print these in ABS. ABS matches the look and feel of the factory plastic, takes a sanded or textured finish well, and handles cabin temperatures without complaint.
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.
