Geeetech G2S Top Stabilizer

Update 12/28/16: I was asked the share the source in order to make modifications, so here it is (careful, it's messy :) ).
Checking the SCAD file I also recalled that I used a bevel library as this was my first work (http://www.thingiverse.com/thing:30336)

This is my first 3d part and I am a beginner at OpenSCAD, so the part is still a bit rough :)

The idea for this part came from seen the "G2S stability improvement" by martinengstrom http://www.thingiverse.com/thing:1817718. T
