Ender-3 Direct Drive BMG BLTouch Stock Hotend
thingiverse
This direct drive mount is a remix of the TEVO Tornado Bondtech BMG direct drive mount (remix), found at https://www.thingiverse.com/thing:3995514, courtesy of QCPassed. It fits the Ender-3 and will also fit the TEVO Tornado as well as the CR-10(S) with the same X-carriage and hotend design. The BMG extruder's outlet was offset 1.5mm in +X and 1.7mm in +Y direction from the stock hotend's inlet. The extruder mount was adjusted accordingly, which was an easy modification thanks to QCPassed providing the Fuision 360 file with his remix. A cable mount has also been added. Please verify that the cable does not touch the right Z-strut when moving to max Y direction. Y-max was changed to 220mm in the Marlin firmware. F3D and STEP files are included as well. Images were added showing how to orient the object on the bed. A support blocker has been placed over the BLTouch mount, including the carriage mount holes. "Support everywhere" is set in PrusaSlicer/Slic3r.
