Shimano Sora plastic shifter wheel

thingiverse

This Shimano part isn't readily available for servicing, so I replicated it. The replica has been successfully installed on a bike that now shifts smoothly. A groove needs to be cut or drilled to fit the shift cable. Printed with 1.6mm wall thickness for smooth and even printing. It's recommended to slow down the exterior perimeter print speed to 10mm/sec unless you have good cooling in place.
