The Land Rover Discovery 3–4 is a vehicle worth keeping right, and a broken door lock knob shouldn't be the thing that lets it down. With your sample on the bench this is a realistic reproduction job.
Why these break
Lock knob splits at the rod socket. Vibration fatigue does the damage: thousands of small flexes add up to a crack at the stress point, usually right where the part clips or pivots.
How we reproduce them
This is a quick job on our end — we take dimensions from your old part, adjust for print tolerances, and run a small batch so you have spares for next time.
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.
Many plastic parts can be recreated, repaired, redesigned, or printed, depending on size, load, heat, material, and available samples. Bring in the damaged part or upload photos for assessment and we'll give you a straight answer before any work starts.
