Updated 20160909: Adjusted the motor holder to the right about 5mm to provide better clearance at maximum Z heights. The first design touched the acrylic. RevF is the newer one (orange in the photos). I first saw MeisnerX's idea to shorten the Bowden tube in early July 2016, and started making mods to fit my rig as I had time to work on it. This is my current version as of late August 2016. I see that MeisnerX has changed his design significantly from his original mounting method on his latest revision, but here's my version, an offshoot of his original design. Similar to his original design, I still mount off the main X axis rods, but flipped the design to move the motor more to the front of the printer. I left the motor mount opening large to allow more air flow around different motors, and added 4 of the 3mmx25mm bolts with 3mm nuts and springs to hold the motor in place. I also added some little clamp pads to stop the screws from marking the stepper motor. I've found that feeding the filament from the bottom or top of the spool depends on the size and weight of the spool. Both ways seem to work fine. I have made several mods to my Sunhokey Prusa i3, the one you see here is the Compact Bowden Extruder (http://www.thingiverse.com/thing:669459) printed in yellow.

Supports should not be required. Post-Printing I drilled out the holes a bit to mount to the horizontal rods, and to make sure that the 3mm bolts fit properly. Nothing else that I recall.
