Ingenuity Extruder for Smart Effector

This is the Ingenuity Extruder for the Duet3D smart effector.

It's a direct drive extruder which features a hollow-shaft Nema-14 stepper motor, Bondtech LGX drive gear, an eccentric breach which is self-locking, an idler wheel where the spokes act as a tensioning spring and a hypoid bevel gear pair, archiving a gear ratio of 37:7.

The whole mechanism features only 4 moving parts: two gears, the idler wheel and the breach-lever, and it weights only 229g!

To make one yourself:

• print lowerhalf and upperhalf from FDM or SLS
• print pinion and wheel from abrasion resistant resin (Siraya Tech fast mecha white) or have it SLS printed from IGUS
• print lever and idler from standard resin
