Why these break
Adjustment knobs crack at the insert. 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
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 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.
