Bondtech BMG Reverse Integrated Drive Gear Assembly
Bondtech BMG Reverse Integrated Drive Gear Assembly
Improve print quality with the reverse integrated drive (RIDGA) for the new HextrudOrt and the new Sherpa Mini.
The R.I.D.G.A. replaces the following drive train items:
Main shaft
Main gear
Set screw
Primary drive gear
Advantages
Precision CNC machined
Super sharp teeth for maximum grip on the grain
Ideal choice for high performance feeding system
Extremely high wear resistance for use with abrasive filaments
Please note, the primary drive is reversed and is not compatible with Bondtech BMG and Voron Afterburner / Strealhburner. More

A collaboration project with an outstanding element from our community
The BMG Reverse Integrated Drive Gear was designed in collaboration with MirageC, the creator of the HextrudORT, to address the runouts of the main shaft assembly and primary drive gear held by a set screw.
As MirageC explains in his YouTube video Extrusion Quality – Mystery issue resolved! the runout of the main double gear and wobbling of the main drive gear contribute to explain the surface irregularity seen in all 3D prints.
To lower said (in)tolerances to a minimum, we made the following improvements:
- main dual gears with tighter tolerances
- pressed fit onto the main shaft with a new method
- also, main shaft and main drive gear are machined in a monolithic steel set
Result? A very meaningful step forward in quality.
