Creality CR-10 E3d mounting bracket with 5015 fan holder

I was struggling to find a good sturdy E3d mount for my CR-10, so I designed this. If printed with 50% infill you will find this to be a very sturdy and effective mount with arrangement for a 5015 fan. I had one lying around from my old anet a8 and these pack more of a punch than the one fitted to a CR-10. I would say I am very happy with this because it it easy to print and you are able to print with support without having too much difficulty removing it from the duct. The whole thing is bolted
