I know, this isn't needed but as pissed as I was with SketchUP not doing what I wanted I digged into it. i´m just using SketchUp for 2 months now I believe. Just testing my old 3D modeling skills and thought why not make a good pulley, might be even possible to print it (some offset of tooth size might be needed if you do so). I know there are ones you can get on the net but this one is made for OpenBuilds from scratch. Any way, not perfect but better than it was: -Ronald OpenBuilds México
