Mountain Bike Bashguard 94mm BCD

thingiverse

My trusty vintage Trek Y-33 has a 94mm BCD crankset installed, paired with a reliable 1x9 gear system. I wanted a custom bashguard that reflected my personality, even if it wouldn't withstand harsh conditions for long. It's great to have unique designs on my bike. Since the 94mm BCD is relatively rare nowadays, I couldn't find any pre-existing models online. Plenty of 110mm and 130mm BCD bashguards were available, but they didn't fit my needs. I decided to design one from scratch, but as a beginner in modeling, I struggled to align the bolts perfectly. That's when I stumbled upon this helpful tutorial: http://www.nothinglabs.com/chainringgen-making-a-chainring-with-open-source-software/. With its guidance, I created a 94mm BCD chainring and then used software to carefully remove material from the edge.
