PETG · £5–8 · 2 working days

Roof vent winder knob

Internal winder knobs on roof lights and vents.

1Why it fails

What goes wrong with the original.

Splines strip out of the knob so it turns without opening anything. A small, cheap part that nobody stocks.

2 · Material

PETG

Indoors, no UV, occasional load. PETG is tougher than PLA and takes the spline detail cleanly.

3 · How it is printed

Orientation, infill and fixings

Spline count and profile taken from your winder shaft. Printed with the spline bore vertical for accuracy.

4 · Price and time

£5–8 · indicative

Quoted properly from your photograph. Ready in about 2 working days from the original or a good picture; batches take a little longer and cost less per part.
