Wire Holder for Prusa I3 MK2S

Since I built my Original Prusa I3 MK2S, the cables from the extruder have been working their way loose from where they enter the Rambo box. No matter how many times I secured them, the cable wrap would slip it's way up and I could see that the cloth covered wires were showing some wear. The single wire tie was insufficient.
This object will add more wire ties holding the wire wrap. So far it's working great, the cable wrap no longer works it's way out.
