Magic Bullet Blender drive coupling

Magic Bullet Blender drive coupling. Coupling Gear to drive the blender, the original coupling attached to the motor shattered. I saved the threaded insert and used it for the 3D print. the things I noticed was to have the insert sticking out the bottom about 5 mil so the coupling doesn't bottom out.* will have to maybe drill in from the side and add a set screw, the plastic did not grip on to the insert and the motor spun the coupling loose from the insert.
