i3 Mk3 Reverse Bowden

I needed a solution to allow me to route multiple spools that didn't use the supplied T holder as I have my printer mounted in a rack. 

This was the simplest solution I could think of and works well for my situation. I dont use an MMU system for this printer but do regularly change colours on prints, this allows me to have spools ready to hand, threaded through ready to swap out. 

Each piece will need a PC4-M6 Bowden connector to finish it off.

EDIT I have taken on board that although this solution was fit for my own purposes and situation, was not suitable for everyone. I have edited the model to allow full height of the Z axis and also for the larger, common PC4-M6 that is readily available on Amazon.
