Informacje o modelu

Material: PETG

Additional parts:

1,5mm copper wire for electrodes
aluminium tube with internal diameter of 23mm and external diameter of 25mm (you can use plastic or other kind of tube but with matching dimensions)

Fuel:

I use hair spray but you can use hydrigen or other flammable gas.

Print settings:

Print with 4 walls and at least 35% infill for strength because it need to withstand high pressure gas from combustion.

I use cheap high voltage generartor from Aliexpress.
