Designed for the following Open Source extruders:

  • HextrudORT;
  • Sherpa Mini;

Why a V2?

The OEM RIDGA V2 allows for ideal engagement between main gear and an 8T or 10T motor gear, while retaining a safe distance between the stepper motor and gear assembly.

When adapting this piece of hardware into your design, make sure to allow for a bit of axial play in both directions, in order for the filament path to retain some level of self-correction.
The bearing facing the motor face should have about 0.4 mm of material between it and the motor face in order for the plastic gear to retain as much engagement as possible.
Please contact us if you have further questions regarding integrations.

OPEN SOURCE EXTRUDERS' DESIGN DISCLAIMER

When assembling an extruder, the sequence of component insertion of the RIDGA differs from the multi-piece version of the classic BMG main drive gear assembly. The drive gear section of the RIDGA can’t be inserted before the gear shaft because it is integrated. Needs a wider hole to pass through.

The Open Source extruder you printed may likely need a custom integration design to support the OEM RIDGA.

Please contact the designer or author of your extruder, or consult within its community, to get help with this.
