Drop in E3Dv6 mod for DaVinci 1.0

Drop in E3Dv6 mount for XYZ DaVinci 1.0.

Based off bdwalker1's design for a drop in mod to replace your Davinci printers stock extruder with a E3Dv6. I lowered the mount for the metal and removed 15mm from beneath the bracket. then added a 15mm spacer/backing above the bracket but under the holes for the PCB. I also cut out the back of the bottom to expose more of the heat sink. The bracket had to be adjusted because of a screw head holding the extruder in place. The fan shroud is identical,
