Real leadscrews are a great upgrade for RepRap printers because threaded rods can be bent, come with burrs, and really aren't designed for the kind of motion that they're used for. This Thing is a pair of X-ends that hold leadscrew nuts. I've also redesigned the bearing column to simplify the design and properly support press-fit Igus bushings (which you can get at http://techpaladin.com), since they were really designed to fit into holes. If you find the holes too small to fit your bushings, you may need to ream or dremel them a bit. The leadscrews and nuts that these X-ends are designed for can be ordered from Misumi. Leadscrew nuts: Misumi part number MTSKR8. Leadscrews: Misumi part number MTSR8-[length in millimeters] Prusa mendels require two units of MTSR8-200. MendelMax printers require two units of MTSR8-350 (360 if using the optional thrust bearing) I've uploaded the .scad files that I modified to make these parts. They may have additional dependencies, but you should be able to grab those from Josef Prusa's github at https://github.com/prusajr/PrusaMendel/tree/master/source If you use Igus bushings, you may be interested in my Igus bushing-compatible Y-carriage bushing holders: thingiverse.com/thing:14593 …And X-carriage: http://www.thingiverse.com/thing:14530 Update 01/02/12: Re-uploaded files with more correct hole diameters and shallower pressure pads in the X rod tunnels to make push-fit assembly less likely to crack the parts.
