Parametric Ball Chain Pulley
thingiverse
I'm designing a parametric openSCAD pulley for my Polargraph machine, which relies on a ball chain to move the pen in a precise arc. I've defined two key variables to control the design: ballChainDiameter and ballChainSpacing. The former dictates the size of each ball in the chain, while the latter determines how far apart they are spaced along the length of the pulley.
