Land Rover Defender Door Lock Knob

A door lock knob for the Land Rover Defender is a typical small-but-annoying part: cheap when it was on a shelf, unobtainable or overpriced now. We've made this style of part before and can usually print yours without drama.

Why these break

Lock knob splits at the rod socket. 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

The process is simple: drop the part in or send clear photos with a ruler in frame, we confirm fit details, and print replacements — often with a little extra material where the original always cracked.

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.
