Bowden spool holder for with extruder mount many spools supported

work in progress:

I have been working on a clean way to mount an spool and extruder together. I took the standard printrbot extruder and the bowden adapter that many of you have .. and mocked up a quick wood version. I tapped the whole that supplies the filament to the extruder so I could insert a bowden tube attachment. I really feel that having a small run of hose on the rear side of the extruder helps to negate any kink in the line as it pulls in filament. Here are the key problems I addressed when building my setup.

1. Allow the filament to follow its natural curl.
2. Keep the Bowden tube as short as possible
3. provide the filament into the extruder with the least amount of kink.
4. Reduce as much resistance to the spool in both directions.

My design has a universal mount on the top that will support fans for the extruder and I envision anyone could make simple adapters for any extruder out there...
Side pieces without the logo's fit better and require less filament to print. I will be modeling a way to connect modular so you could connect them together to build an array of spool holders for multiple extruder setups.

PLEASE PUBLISH YOUR MAKES!!!
