Summary

Replacement Knob for the now obsolete Ariston originals

Instructions

Printed in PLA with no support, 25% infill and 0.21 layer height. Keep the printing speed fairly low I think I used 2000mm/Min or 33mm/Sec

You need three of these knobs for the complete set. Once printed and fitted to the boiler a small marker needs to be added as a pointer, I used a tiny blob of white car paint (I printed the knobs in Black PLA)

These are much stronger around the spindle mounting point than the original which break after about 12 months of use.
