About this 3D model

I wanted to be able to tension my Y belt without having to work underneath the machine, so I decided to try adding a tensioner to the Y end idler. I have this mounted on my MendelMax and it seems to work very well. In fact you have to be careful not to over tighten it. Edit, March 1, 2012 I fixed the mounts with the ridge by eliminating the ridge around and above the hole.
