Pfaff Pulley Adapter

So i put a servo on my pfaff sewing machine and it was way to fast even on the lowest setting. So i made this to go on the sewing machine pulley to slow it down and to have more control for stitch by stitch. People make an aluminum version of a complete pulley to accomplish the same thing but i didnt see the need for that. Please feel free to adjust it for
your needs. Printed with pla and 50% infill. Works like a dream slowed it down 50%..

designed to bolt together with m3x30 socket head
