Prusa Air 2 X carriage - Micron direct drive extruder

Got asked by a friend to see if i could work something out to fit the Micron extruder on a Prusa Air 2

Have taken my earlier X carriage design http://www.thingiverse.com/thing:154258 and re designed the top carriage plate to accommodate the micron extruder and still maintained the standard 2 holed spacing for other extruders ( Gregs wades etc)
This is concept Rev 1 and seems to work great. Although with the fan at the front it is difficult to see what is being printed and next revision wil
