Wanted a chain guard for a 50t chainring to protect my pants from getting dirty. Diameter is 217mm (about 8.5 inches) with a 4 bolt pattern. Each bolt hole is 104mm from its opposing hole, aka a 104 BCD. NOT EVERY CHAINRING IS THE SAME. Please measure your chainring dimensions twice to ensure it'll fit.
Print settings I used:
.4mm nozzle
.2mm layer height
Top and Bottom pattern: Archimedean Chords (you can do whatever you want here, just worked for the circular pattern)
Printed in PLA since the color I had matched the bike, but any material should work.
