Modelled on the broken one in my kitchen. Not sure what exact Zanussi model, but the D-shaft measures 6mm nominal diameter with depth of approx. 17mm. It's a comfortable press-fit, and deep enough to engage the igniters when pressed.

Example print settings per photos: 

  • Elegoo Centauri Carbon, 0.4mm nozzle
  • Tinmorry Metallic PETG @ 250°C 
  • 0.25mm support Z distance (for cleaner separation).
  • Variable layer height (Min 0.12mm only for the detail in the flame symbols, which I have not included in this upload because they are not my own)
  • Ironing all top surfaces, 30%
  • Inner/Outer/Inner wall order
  • 4 wall loops, 5 top/bottom shells
  • 25% infill
  • Painted tree supports on the large flat overhangs only (not inside the dome) - see pic 3 & 4 for example

Remember to align your seams! I forgot and it's visibly off-centre. I can't be bothered printing another example though.

Better surface finish may be achieved by orienting the top of the knob on the print bed, but I haven't tested this for supports.

I wouldn't recommend PLA for this due to nearby heat & flame.
