Dragon UHF EVA3 adapter (heatset) - Remix with space for heater cable

It takes a scavenger hunt to find an acceptable DragonUHF adapter for EVA3.  And the one I found has cable-routing issues.  I modified it to give extra space for the heater cable to come out the side.   It's still not perfect but it's good enough!

THIS IS NOT A DIRECT REMIX of the linked EVA3 dragon hotend adapter – that is for the non-UHF version.  But I found the UHF adapter via that printables model, in the comments there's a note about finding the UHF model in the EVA github repo, for which Issue #94 has a link to the CAD of an experimental version, lol…

THAT is the model I remixed :sweat_smile:

Beyond added a cavity for the cables to come out, I added “HEAT” and “THRM” to identify the orientation I used in my setup which has been working great.  When looking at the front of the printhead, the HEATer cable comes out the right side, and secured using the built-in ziptie channel.  The THeRMistor wire comes out the left side which I routed up and over the top of the printhead, in front of the extruder.  

NOTE: I have made the license non-commercial because I am aware there are some IP issues with this model but I don't fully understand them.  I figured more restrictive was appropriate.  If you believe this is not correct, let me know and I'll change it.
