Pear effector - v1

UPDATE: have a look at a new, improved version http://www.thingiverse.com/thing:2286944

This effector were inspired by Kirill91's one (http://www.thingiverse.com/thing:1569106), designed for E3D-V6.
I wanted one for E3D-V5 (and E3D-V5 clones), so I made this.
Furthermore, my Kossel mini reached 296mm max height build cylinder, I needed 300mm at least: now with this effector I can print up to 335mm.

Pay attention: I used small axial fan (http://tinyurl.com/l3kpx46), 25mm X 25mm X 10mm.
