Since I am currently experimenting with a wind turbine with a Nema 17 stepper motor as generator, I needed different ratios. You can cut the belt to the required length yourself (I am very impressed how much load you can send over this small belt). There is a simple reason why an M8 hole is used on the opposite side! Because with it it is possible to use the inexpensive Inline Skate ball bearings. * https://www.ebay.de/itm/Polyurethane-Conveyor-Belts-PU-Round-Drive-Belt-Meltable-Cord-Dia-2mm-to-12mm/173530366142?ssPageName=STRK%3AMEBIDX%3AIT&var=472218264938&_trksid=p2060353.m2749.l2649 * https://www.ebay.de/sch/i.html?_from=R40&_sacat=0&_nkw=inline+skates+bearings&LH_PrefLoc=2&_sop=15 * !!!I think the Pulleys also work with the 4mm belt! (but so far untested)!!! Addendum: Because for whatever reason the Thingiview doesn't work right now. The Nema17 Pulleys have the phase of the shaft to lock them. Have fun, like, and share your makes...

Den Riemen könnt ihr Euch in benötigter länge selbst ablängen (ich bin schwer beeindruckt wieviel Last man über diesen kleinen Riemen schicken kann). Warum eine M8 Bohrung auf der Gegenseite verwendet wird, hat einen einfachen Grund! Denn damit ist es möglich die kostengünstigen Inline Skate Kugellager zu verwenden. * https://www.ebay.de/itm/Polyurethane-Conveyor-Belts-PU-Round-Drive-Belt-Meltable-Cord-Dia-2mm-to-12mm/173530366142?ssPageName=STRK%3AMEBIDX%3AIT&var=472218264938&_trksid=p2060353.m2749.l2649 * https://www.ebay.de/sch/i.html?_from=R40&_sacat=0&_nkw=inline+skates+bearings&LH_PrefLoc=2&_sop=15 * !!!Ich denke das die Pulleys auch mit dem 4mm Riemen funktionieren! (ist allerdings bisher ungetestet)!!! Nachtrag: Da warum auch immer die Thingiview gerade nicht funktioniert. Die Nema17 Pulleys haben die Phase vom Schaft um sie einzurasten. Habt Spass, liked, und teilt Eure Makes... SG
