Timing Belt Pulley GT2 80t 6mm sleeve for 20t pulley

HINT: Voron moved away from printed Z gears. This is only a makeshift alternative

Non Printed parts needed:

* 5 x M3x8mm flathead screw (https://de.aliexpress.com/item/4001338395909.html)
* GT2 20 tooth pulley 6-7mm width with removed cap (https://de.aliexpress.com/item/4001338395909.html) (You can remove the caps yourself very easily)

This 80teeth belt pulley for 6mm belts is a cheaper alternative to the relatively expensive full aluminum pulleys like https://de.aliexpress.com/item/32783298317.html

This pulley needs a beheaded aluminum/meta GT2 20 tooth pulley as a core element. It will be fixed with 5 M3x8mm flathead screws.

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.)

I will report on durability when they have some more duty hours on my printer :)

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.
