Pfaff Pulley Adapter

thingiverse

So I installed a servo on my Pfaff sewing machine, but the speed was still too fast even on the lowest setting. To gain more control stitch by stitch, I created this pulley attachment for the sewing machine's pulley to slow it down. Since others have made an aluminum version of the entire pulley to achieve similar results, I didn't see the need for a complete overhaul. Feel free to modify it according to your needs. Printed with PLA and 50% infill, it works like a charm, slowing down the machine by about 50%. This design uses M3x30 socket head bolts and nyloc washers to bolt together securely.
