9mm belt has 50% higher tensile strength and 50% less stretch than stock
Reduces ringing in prints
Easy to tension and won't stretch out like the stock 6mm belt

Reuse the stock M5 mounting screw and washer with the included M5 flange nut/spacer and 9mm idler pulley, then assemble as shown below. Assemble the belt in the same manner as stock, making sure to align the stepper drive pulley. When mounting the below idler assembly be sure to do the final tightening using the nut so the pulley retains a bit of play and doesn't bind.
