This is a STL of the shaped cam pin for a M1337 print project. I created this to have a consistent geometry across all six bolts for testing / troubleshooting purposes. I have printed them out of PA6-CF, PETG-CF, and PLA+ all at 100% infill and .16 layer height. These pins don't really bear any load in the action cycling so they should be safe to use and far easier than consistently cutting / grinding steel cam pins to the right shape. As with anything like this, use at your own risk.
