Box Trailer Jockey Wheel Clamp Knob
Salt, sun and vibration are brutal on Box Trailer plastics, and the jockey wheel clamp knob usually gives up first. A tougher printed replacement breaks that cycle. We've made this style of part before and can usually print yours without drama.

Why these break
Clamp knobs strip and the jockey wheel slips. Heat cycling is the killer here: years of expanding and contracting work-hardens the plastic until a routine bump becomes the final straw.
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 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.
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.
