I'm trying to print a prusa mendel for a friend but plate one doesn't slice properly in slic3r, none of the holes for the sensor mounts print and the holes for mounting the slide rails on the x-axis idler and mount are not filled on the bottom are some of the problems I was having. I decided to print some of the parts individually to see if that would work, and it did except the lm8uu brackets don't print on the x-idler and motor mount. I've attached a rendered image of the parts in openScad since it seems that that's how the parts are in the source. I'm not sure if this is a bug or part of a redesign. I suppose I could use zip ties to keep the bearings in place but the snap-in solution was working great for me. Anyone know anything about this or have a stl file for the parts that works in slic3r?
