I was playing with sprockets and chain for driving L3-G0's motors (http://L3-G0.blogspot.com - My full size Lego R2D2, video on [Youtube](https://youtu.be/R9TgYUSNmPU?list=PL7uobZWs1n9jt_cGMIK8vOsQ37n-L-Q73)). Having difficulty finding a sprocket supplier, I decided to print some, but I wasn't able to find an OpenSCAD type sprocket library.
This "knows" about many types of ANSI chain, Motorcycle Chain, and maybe Bicycle chain, but I've only tested with ANSI #25 roller chain because that's what L3-G0 uses.
Sizes are: #25, #35, #40, #41, #50, #60 & #80 roller chain, and 420, 425, 428, 520, 525, 530 & 630 motorcycle chain. You can comment if the other sizes work for you (& if you had to tweak the fudges).
L3-G0's complete now, so check out [his blog](http://L3-G0.blogspot.com) & share with friends. Also please give a thumbs up on his [video channel!](http://youtube.com/subscription_center?add_user=myL3G0)
