This is a chain protection ring for a Shimano Alivio 42 teeth chain wheel.
Replaced my chain wheel and the old protection ring didn't fit anymore, couldn't find a good replacement either so I made one and printed it.
Print the protection ring in your favorite plastic and attach it with 4 x M5 15mm screws and 4 x blind nuts.
Change the Openscad file to fit other chain wheels.
