Wade's extruder to bowden cable, for every hole

I made this part to check customizer and play with openscad.
It is based on this: http://www.thingiverse.com/thing:36240 from Petehagoras
The dimensions for the holes are taken from jonaskuehling's openscad model http://www.thingiverse.com/thing:18379 (Greg's Wade reloaded)
The dimensions are tight, so i don't know if it will work out of the box.
I didn't check if already existed for every hole.
I'm not familiar with licences so i'll keep the original.
