Olympic Awning Rafter Knob
Olympic made solid gear, but the small plastics are always the first to go — and the awning rafter knob is a regular on our bench. We've made this style of part before and can usually print yours without drama.

Why these break
Rafter tension knobs crack in the sun. 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
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.
