A simple mount which holds the Bowden cable and your extruder. It "snaps" onto the top rails of a Prusa. I designed this so that I could use a Bowden extruder while still having my filament spools mounted to the top of the machine. I mounted this to the front side of my Prusa but it could also be mounted in the other direction.Print it out and snap it into place on the top rails of your Prusa. Optionally, secure it with zip ties. Then just snap the Bowden cable in and attach the extruder.
