About the timing pulley maker

Make a timing pulley for the belt you have, with the number of teeth you need, flanges, a hub and a set screw hole.

  • Printed grooves vary: wrap the belt around the first print before making more.
  • Use a D-shaped hole for motor shafts with a flat.
  • More teeth wrap the belt more gently and last longer.
