Sublime, for the 3mm you recommend... is that the filament diameter... or a retraction length?

You didn't say what printer, or what type of printer?
Filament is not hydraulic --- fluid vs solid.
I would disagree with even 90 deg bends with hydraulics.
The hotend (output nozzle) is always moving!
Sweeping bends in transit tubes in all areas, even supply to extruder.
Shortest route with large radius bends in all positions without twisting.
Run extruder without hotend for smooth, resistance free filament movement.
Extruder directly above the hot end midpoint.
Think of it as transfering the push of the extruder thru the bowden tube
----- with ALL force transfered to hotend tip!

So should the output of the extruder pointing straight up in the air and then arch 180 back down to the x-carriage?

I'm building a second printer changing quite a few things as it slowly progresses. The new E3D v6 inspired me to to consider going for a Bowden extruder. I was wondering about optimum placement of the extruder motor and what people have had best results from. It would seem best to keep the tube as short as possible so was considering a swivel mount attached to the Z assembly that would go up and down with the X carriage. Does that sound feasible?
