Nema 17 (5mm) to 8mm Pulley set for 2mm PU-Belt -- Nema 17 (5mm) zu 8mm Riemenscheibensatz für 2mm PU-Riemen

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.
