It will be fixed with 5 M3x8mm flathead screws.</p><p>I use these for my voron 2.4 z drive idlers. (The pulley from reddit that served as inspiration pully from the reddit thread does not fit in the voron z drive.)</p><p>I will report on durability when they have some more duty hours on my printer :)</p><p>I would suggest to print these in ASA or ABS and 100% infill. I would not recomment using PETG or PLA. They will be under heavy duty and any flex will result in weird behaviour.</p>
