Solidoodle extruder head wire bundle guide
This is a guide to keep the extruder head wire bundle from rubbing against the Y axis band when the head is working on the far left of the platform. It will guide the wire bundle up and keep it safe and snag free, and release it when the head moves away. It will not interfere with the extruder head nor any of the workings of the Y axis drive train.
The wire bundle guide slides over the top rail of the chassis. It may interfere with the case cover when it is installed, as a small part of it sticks above the chassis rail. Also, you may have to remove the tape that holds the LED wire bundle, as they often run the wires in the center of the underside of the top left rail.
