Sewing machine pulley_sailrite ultrafeed clones

This is a larger drive pulley (2 times the standard size) for the sailrite ultrafeed and similar clone machines that are sold under various brand names (mine was called TuffSew)

I chose to make my own design after seeing the price for their injection molded plastic pulley (+30$
