Filament Pulley for Rostock
Published on November 7, 2012
This is a remake of the pulley designed by Grabercars with the gears replaced and an added hole for the drive filament to go into. There are others who have used simmilar mechanisms to control an axis. I hope to use floss with mine in order to reduce the cost of finnishing my machine and keeping the wife happy (I am sure she is getting sick of my daily trips to Fastenal).
Print as many as you need, attach the driving filament by running it through the hole and winding each end in opposing directions, connect one of the free ends to the proximal end of platform and run the other end arround another pulley and then attach it to the more distant end the platform.
