I do have the design for dual e3d, however, it doesn't work properly. The mount is laid out the same as this one and makes use of one 30mm fan to cool the hot ends, the problem is that that small fan is inadequate at cooling both hot ends so they jam up. It is also awkward to level each hot end. In the end, i just gave up and brought a Chinese clone chimera hot end. I will be happy to send you the files over though if you want to edit them.
