About: An old project, revived to quickly share. For anyone looking to design a chain cog/chainring, feel free to use the .F3D or sketch constraints below. 

Hollowgram spline as a bonus. I machined this spline a few years ago and needs some minor tweaks. If you're milling, prepare for some wear offsets.
