Creality Ender 3 BMG direct drive mount
thingiverse
This mount requires the Ender 3 Direct Drive Upgrade Kit available on eBay or Amazon. It utilizes the two mounting holes used by the direct drive kit but instead of using the original extruder, you use a Bondtech or Bondtech clone along with the original extruder stepper. To utilize this setup, you will need to adjust your e-steps in firmware to accommodate a BMG/Bondtech as it is a geared extruder. I employed 50% infill for added rigidity, though you likely won't require it. UPDATE: mount_beta2.stl is an updated version of the mount. The BMG is now positioned more centrally over the hot end, and the overall structure has been strengthened. Additionally, printing with supports will be necessary for this revised design.
