I'm still working on this project and refining the design as I test it and gather feedback. Future updates will include adding pictures to help illustrate the design. Ongoing Edits and Changes: Apr. 23, 2019 - I added an untested mount for the NF THC-01 3 in 1 out hot end, which is still being tested. Dec. 9, 2018 - I corrected an error on the Xmin carriage parts where the rail sits, removing the mistake and re-uploading the Xmin parts. Nov. 16, 2018 - I've now tested the 8mm Y rod parts and confirmed they perform as expected. Nov. 13, 2018 - I added a hot end and fan duct mount for the XCR 2in1 dual extrusion hot end (https://www.aliexpress.com/item/3DSWAY-3D-Printer-Part-XCR-2IN1-V2-Color-Switching-Hotend-Two-Color-NV6-Heated-0-4/32911051621.html), other fan ducts may work but may need to be shortened, use my uploaded one for approximate sizing. Nov. 12, 2018 - I made a quick addition to the X min joiners, adding an offset to help engage the switch earlier since it wasn't engaging before the housings were touching. Nov. 2, 2018 - I made a quick adjustment to the carriage, which had trouble printing and slicing due to thin walls around the holds for the m3 bolts that hold the belt tensioning bracket. I also added (untested) mounts for an E3D Titan and BL-Touch. Summary: These parts are designed for a Hypercube conversion to using MGN12H linear rails for the X axis linear movement rather than standard steel/aluminum/carbon-fiber rods. The goal was to keep the parts simple and printable without supports, resulting in a motion system with fewer parts that seems more rigid than the stock design. A demo can be seen here: https://youtu.be/igHfxheWQmU There are parts available for both 8mm and 10mm Y linear rods, and the joiners utilize 20t idlers. I made the mounting for the MGN12 onto the joiner fairly compliant to ensure sizing is more forgiving. You'll want to have at least two bolts for each side to prevent any pivoting. Note that the carriage and hot end mount directly to the MGN12H carriage, so the spacing of the mounting points is not standard Hypercube. Additionally, a quirk is that the fixed and adjustable belt mounting to the carriage is reversed from standard Hypercube, although it shouldn't matter. This carriage also has the integrated belt tensioner system from Anukwolf.
