A Remix of the Rostock Carriage Igus/Traxxas mod. I modified it for several reasons: the endstop-screw is - looking on the top - moved closer to the center between the smooth rods and not far in front of like in most other designs. on some rostock designs this is easier to mount, especially, when you have to front-mount your belts. i also slightly enlarged the hex-nut holes. when they are to tight, the material tends to break when tightening the screws. the clamp should prevent the belts from putting to much force to the carriage and loosening it. It is not just a desing feature, if the belt is tighten properly, it WILL pull the screws outwards a bit and loosening itself, even with washers and if screwed tight!printed with .5 nozzle, .3 layer height and 25% infill @60mm/s
