Spool Mount Meddley

Using parts of two things, I manage to get the ideal spool mount for a Prusa Mendel 3D printer. I used the top part of http://www.thingiverse.com/thing:32320 and the bottom part of http://www.thingiverse.com/thing:30742 .InstructionsPrint 1kgTopPair.stl from http://www.thingiverse.com/thing:32320 and two Spool_vertical_mount.stl of http://www.thingiverse.com/thing:30742 . You will need 2 threaded rods of 8 mm x 20 cm and 1 smooth rod of 28 cm. Having bushings for the spool reduce a lot the friction and the force needed to unwind the filament.
