Mytee Eco-17 replacement Jet Knob. The ones on my machine got broken over the years and so I drew these replacements. I added text to mine to show the direction to tighten.
Print Settings: Printed in PetG 4 Walls, 20% infill.
Post Printing: You will have to remove the screw and and leftover plastic from the previous knob, then take the screw with a pair of pliers and a heat source I.e Lighter or torch and heat the head of the crew for 30 seconds to a min and immediately push the heated head into the whole of the new printed parts setting firmly. Let it cool for a few minutes before using.
