About this 3D model

This is a modified version of "Ultimaker Wade's Accessible Bowden Bracket" by stcredzero : http://www.thingiverse.com/thing:14822 I remade it in openscad for easier modification, and added : - A bigger hole for the pneufit tube adapter - the original was not large enough to allow for easy/secure bowden PTFE tube attaching/detaching. - Added recess in the two M4 extruder attach holes, so we can use shorter bolts. I used https://github.com/daid/OpenSCAD-polygon-editor to build the openscad file from the original stl.
