Any questions just let me know

do they fit this requirement for the prusa? if so I'll take 5

NEMA 17 bipolar stepper motor Stepper Be sure to get ones with at least 20mm of shaft length. Shorter shafts require modifications to the X pulley assembly and Z motor couplers. One of the five motors, for use with the extruder, should be capable of creating a holding torque of at least 40Ncm, at the very least.
