E3D Volcano mount for Rigidbot

Here is my quick and easy solution to add a E3D Volcano with a V6 heatsink and bowden as second extruder to an existing Rigidbot. For the cold part you can use for example this extruder: http://www.thingiverse.com/thing:617279.
But I still have to test it that part is up to speed when pushing the Volcano to the highest speeds (at least not with a 36 oz/inch motor). I have a new motor ordered but also might remix this thing http://www.thingiverse.com/thing:711401 to fit on the rigidbot.
The pictures are from an older version (and a somewhat crappy print)
