Ball-Chain Pulley for Polargraph
by JohnA, published
This is a ball-chain pulley for 3.5mm ball chain, intended for use as part of a Polargraph:
Regular metal ball-chain was easier to locate versus the type that Sandy had used on his Polargraph.
I use a slightly modified version of Ed's stepper motor mounts as well:
The ball-chain I'm using came from here: http://www.kitkraft.biz/product.php?productid=8353&cat=&page=2
Update: The gondola I printed for mine is here: http://www.thingiverse.com/thing:12557 - and it works!
Pulley is sized for a 5mm shaft, and has a 3mm bolt / nut setup for tensioning on the shaft. If this doesn't match your stepper, edit the .scad file and change it up.
