About this 3D model

I edited the SCAD file from openhardwarecoza to work with my Jhead-Lite Hotend from Ohioplastics. The first one I printed didn't have the relief for the idler, so I had to trim it down to fit. It seemed to work well until my Stepper died. I haven't printed this one yet. Edit: I had it printed at work. I will test for fit tonight. Edit: 5/15/14 Added a relief for the Strut.Edit: 5/19/14 Corrected Mistakes
