Folger Tech FT-5 filament guide ("reverse bowden") brackets

During initial testing with the FT-5, I noticed how the hotend movements are also dragging filament off the spool. Given the high travel speeds of the x-y carriage on an FT-5, I didn't feel it was a good idea to let the same movement also unwind a heavy filament spool at the same time.

I also own a Kossel, which has a a bowden setup where the extruder is mounted on the frame, a bowden tube feeds the filament to the hotend. For the FT-5, I didn't plan to move the extruder, but simply having a bowden tube still means that the distance from the spool to the hotend stay the same, regardless of the hotened carriage position.

So I made a clip to mount on the real, above where my spools are, with a 5mm pneumatic connector, connecting a standard PTFE tube long enough to reach from the mounting position to every possible position of the hotend carriage.

The PTFE tube runs to another pneumatic connector on the hotend carriage.
I wanted to have the pneumatic coupler as high as possible
