What we don't take on
We don't reproduce or modify parts whose failure could disrupt a safety
system, cause injury, or cause a loss of control.
In practice that means no brakes, steering, suspension, fuel
systems or restraint components, nothing that carries load or
holds a wheel, and nothing inside an intake tract. The same principle
applies on the water and in the air — steering and control linkages,
through-hull fittings, and any aircraft part, certified or not.
It also rules out some parts that look purely cosmetic: interior trim
sitting in an airbag deployment path is engineered to break a specific
way, and a printed replacement isn't.
If you're not sure which side of that line your part falls on, ask —
it's usually a two-minute answer, and it's a conversation we'd rather
have before you ship anything. Full details in our
terms and conditions.
