The parts were made for Powerspec 3D Pro and 3D Ultra printers that have a flat black plastic piece on top of the extruders and where filaments go through the holes. They were supposed to keep the wires from bending as the extruders go back and forth. The Flashforge Creator Pro at the program for mentally handicapped people has a plastic piece on top of the extruders with a short cylinder supposed to hold the wires but it didn't work.
