Block and Tackle
Description
I Needed A Block And Tackle To Lift Hay Bales In My Shed. I Found This One Here By Mysabre73: Http://Www.Thingiverse.Com/Thing:963214 But It Was Too Big For My 150X150 Printrbot Simple. I Got It Printed At 90% But Figured I'D Rather Have 608 Bearings On The Pulleys So It Ran A Little More Freely And Lasted Longer. So I Whipped Up Some Openscad Files And Got It Done. Update 1: I Found Out How To Join Circles By Tangents Rather Than Direct To A Perpendicular Radius. Version 2 Of The *.Scad And *.Stl Files Use The 'Hull' Function. I Haven'T Printed This Version Yet, But It Should Be Neater.
