Makerslide Dual Extruder mount for Budaschnozzle Hot End

I am currently building a Mendel Max of all Makerslide on X,Y,and Z and wanted to go with Dual extruder due to having a much bigger build area. I love the quality i get out of my Budda so in order to make it double, I went off Lulzbot TAZ Dual Extruder mod - ( http://www.thingiverse.com/thing:106147) and a standard Makerslide carrage and smashed them together in sketch up. It slices fine, but I have not printed it yet, Still building the large mendel max.

Please offer any improvements you
