90 degree angle for bowden extruder

I had the need to have my extruder point its filament to the top of the printer, so i designed this.
Never tried it, but it should work.
Its designed for 20mm alu extrusions and M5 Screws for mounting the thing itsself, but M3 for the bowden extruder (see thing #275593; http://www.thingiverse.com/thing:275593).

EDIT: i have printed the "easier to print" version and it works well. :)
