Trakmaster Awning Rafter Knob
Salt, sun and vibration are brutal on Trakmaster plastics, and the awning rafter knob usually gives up first. A tougher printed replacement breaks that cycle. With your sample on the bench this is a realistic reproduction job.

Why these break
Rafter tension knobs crack in the sun. 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
Reproducing one is straightforward for us: we measure your sample (broken is fine, as long as most of it is there), match the profile, and print in a tougher modern material. Turnaround is usually within the week.
We print these in ASA. ASA is the UV-stable cousin of ABS — it holds its colour and strength through years of Australian sun where the original plastic went chalky and brittle.
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.
