Prusa MK4 Reverse Bowden Filament Guide

I keep most of my filament in dry boxes so I wanted a way to use a reverse bowden tube with the Prusa MK4. I remixed the original filament guide adding 2 holes for a bowden tube. 

The smaller hole is used if you don't want to run the bowden tube all the way to the extruder. 

The larger one allows some movement if you want to run it all the way, I recommend adding a PC4-M5 quick connect fitting for that setup.
