Why these break
Bump-feed cap tabs wear and the cap flies off. The original was moulded thin to save cents at production volume. That was fine when the plastic was fresh — twenty years on, there's no margin left in it.
How we reproduce them
Bring in the broken part and we'll reverse engineer it — usually with a design tweak that addresses why it failed in the first place, not just a copy of the weak original.
We print these in Nylon. Nylon is slippery and fatigue-resistant, which makes it the right choice for parts that pivot, slide or flex thousands of times.
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.
