UPDATE - Added mount for left hand side of printer....
This mount is designed for the GeeeTech I3 ProB Acrylic printer. It will allow you to move the MK8 extruder to the top right hand side of the printer for use in a Bowden configuration. I purchased the aluminium left hand version of the extruder from GeeeTech for mine. However you should be able to use any extruder that will fit on a standard neema stepper mount.
The mount has the holes in the same location as the acrylic rod guide at the top of the printer and you will need to use longer M3 screws to accommodate the extra thickness of the mount itself. However there are a heap of those left over when you assemble the printer kit....
I am using this in conjunction with the GeeeTech I3 ProB E3D V6 Mount with Dual 40mm Fan Mounts at: http://www.thingiverse.com/thing:2170993
