Hypercube Evolution HEVO MGN12H Linear Rails BMG Direct Drive

thingiverse

After searching, I couldn't find a linear rail solution for the Hyper Cube Evolution that met my needs. Instead, I used a modified version of my BMG mount and designed a MGN12H carriage mount for the BMG direct drive extruder setup. For the motor mounts, idlers, and XY joiners, I modified the model from https://www.thingiverse.com/thing:3786629. I've included all the SCAD files that I modified to create mounting for the rails. The original used MGN15 for the X axis, which I changed to fit an MGN12H. This design is specifically made to fit my Hypercube Evolution Setup, which includes: * CoreXY on Rails * Sensorless Homing on X & Y * BMG Direct Drive Setup * X Rail without added support * 5015 part cooling fan * BLTouch Z Probe (Probe Offsets are 36.5) * Wire management on extruder When printing, I recommend using PETG or ABS but high-density PLA should also work. The recommended settings include: * 0.4mm nozzle with 0.5mm line width * 4 shells * 4 top and bottom layers * 30%+ infill * 0.2mm - 0.28mm layer height (your preference) For the rails, I used 400mm on the Y and 450mm on the X. These are the same rails that I purchased from https://s.click.aliexpress.com/e/_sDIkn5. They were surprisingly smooth and much better than I expected. I originally printed the parts in PETG for fitment and testing, but after some tweaking, I printed the final parts (except for the XY joiners) in ABS. The BMG mount used 3mmx5.5mm nut inserts, while the X rail is a press fit into the XY joiner or can be locked in place with M3 screws and nut inserts. This setup is fully functional but I plan on redesigning the XY Joiners from scratch at some point. Feel free to ask any questions and make sure to post your makes!
