This is remixed for typical treadmills motors. You know the likes of non-commercial or high end ones rated 2-3 HP and with a 1/2 inch 13 TPI left handed thread for flywheel.. You will need to drill a 4mm hole and use either a M4 bolt or a rolling pin to fix the motor pulley. Pretty easy after threading the pulley to the motor. It should be printed in .1mm layer as it has threads. I feel like the original spindle doesn't has the T5 tooth profile(the motor pulley does), So I remixed a T5 35 teeth one which seems have a better belt fitting. It also results in a slight larger diameter (that will give more clearance on the back for gas spring installation etc.) Also as bonus Include a box for long liner potentiometer that typically is seen in early day treadmill.
