Shimano Sora plastic shifter wheel

This Shimano part is not readily available for service so I replicated it. It's been successfully installed in a bike which now shifts normally. A groove must be cut or drilled to accommodate the shift cable. Printed with 1.6mm wall thickness for smooth circular printing. Recommend slowing exterior perimeter to 10mm/sec unless you have good cooling.

Printing in ABS although PLA and other materials may also work.
