This is a concept part which adds some features to the original printrbot x-motor mount. (It's based on the V2 release of the printrbot motor mount.) X-Motor Changes: *Z-Endstop Bolt Holder - the nut capture on the side will hold a nut for a long #6 (SAE) bolt which will trigger a mechanical endstop glued to the side of the z motor *Access To Bottom Two Motor Mount Bolts - Added slots to access the bottom two motor mounting bolts with an allen wrench. *Adjustable X Rods - Added nut captures for bolts to push the x smooth rods further apart, in case they are cut too short (this will cause leadscrew wobble if they are even 1mm too short). I think it's best to use a jig to adjust how far apart the bases are from eachother, then fine tune how far apart the x-rods are with this feature. *Thicker Nut Trap - Raised shoulder on the nut trap for the leadscrew according to droftarts's suggestion. *Adjusted Leadscrew Nut Chamber - The nut chamber is now the same size as the idler's. 8mm nuts should fit inside of it. X-Idler Changes: *Thicker Nut Trap - Same as x-motor mount. *Moved idler bolt up 5mm due to droftarts's suggestion. Update: Woops, I moved the idler bolt down instead. Fixed. Update 2/24: Jsturm noticed the bottom hole from the x smooth rod did not line up exactly (off by I think .1mm) between the idler and the motor. Fixed Update 2/25: Jsturm also noticed an issue with Brook's nut chamber for the leadscrew-nut. It was a different size on both of the x-ends. He also noticed an 8mm nut fit in the idler, but not the motor mount's chamber. Fixed by copying the leadscrew-nut chamber to the x-motor mount.
