Parametric roller chain elements

thingiverse

Revamp the roller chain with basic components such as utilized in bicycles and scooters. This chain works harmoniously with parametric sprockets (http://www.thingiverse.com/thing:7918). To build it, you need to use three primitives: 1. chain_link(pitch,diameter,hole,thickness) - accepts parameters like pitch, end circle diameter, hole diameter and link thickness. The picture can guide you in understanding the construction. 2. roller(inner_diameter,outer_diameter,width) - essentially a tube. 3. pin(); essentially a cylinder. Use these instructions to create your own roller chain.
