Pull-Chain Pulley

thingiverse

A Basic Pulley System. It Prints Well with PLA Filament. Update: Version One Had a Few Issues. The Chain Slipped Off on My Daughter, and the Axle Broke When She Was Reattaching It. So, I Made Some Changes for Version Two. I Thinned Out the Pulley to Half Its Original Thickness, Which Should Give the Shorter Axle More Strength. Additionally, I Added a Spring-Loaded Chain Retainer to Keep the Chain in Place and Prevent It from Jumping Off the Pulley.
