This project was a collaboration between Michael Bourque and Derek Rowland. Although it was modeled from scratch, it was heavily influenced by Matt Bevo’s fantastic “CR6 SE Direct Drive BMG Adapter” found on Thingiverse.
Our aim is to make a free and easy to print direct drive kit for the CR-6 SE that is strong, rigid, while avoiding problems plagued by the bowden tube and strain gauge systems.
As you may know, direct drive is all about rigidity and no backlash. In our testing this produces excellent prints with no stringing or issues plagued by less rigid systems. It does not break or interfere with the strain gauge. It’s a great upgrade you can do yourself.
You will need
BMG V2 Clone
Existing Extruder Stepper Motor

Required Printed Parts
dd_bmg_adapter.stl (or dd_bmg_adapter_thin.stl for standard length BMG bolts)
strain-washer.stl
bowden_connector.stl
Optional Printed Parts
filament_sensor_top.stl
filament_sensor_bottom.stl
2 PC4-M6 Pneumatic Couplers

Note: We have also included a .step file so you can modify the bracket if needed. Please share what you do so we can continually improve the design.
How to Print
Use a stiff filament material like PLA, PLA+, or PLA Carbon Fiber. PETG is not recommended as it is too flexible. Use Cura or your favorite slicer; recommended settings and orientation of parts are shown below; print as shown to meet design intent.
Post-Printing
While the design includes rounded edges, be sure to manually remove all support, burrs, and break any sharp edges after printing.
How I Designed This
Designed in Creo 7
All of the design was done from scratch using Creo Parametric 7.0 from PTC
