Deluxe pulley for strings and ropes (openscad / parametric)

Description

This Is An Openscad Script To Generate A Pulley For Strings And Ropes. It Uses A 608 Zz Bearing (The Cheapest And Most Common Ones, Used For Skateboards And Rollers, About $1-2 On Ebay). With The Source, You Can Tweak Most Of The Properties, Or Use Another Kind Of Bearings. The Groove Cover, Attachment Leg And Top Housing Are Optional. I Use These To Lift Bags Of Bird Seed In My Garage, Out Of Reach Of Mices! The Pulley Is To Be Screwed Or Nailed To A Support On Its Own Axis. However, The Optional Top Cover Makes It Possible To Hang It. The Last Picture Show How I Reinforced One That Lifted About 50Kg.
