CR10 40mm Cooling Duct Mount with Nut and Grub Screw Indents

I modified Timah81's already beefy mount to be a bit more beefy. :) I wanted to run m3 bolts through the top part of the fang and fan with nuts on the back side to really lock it down. Once you get the fang on there with a radial fan and EZABL, it really needs to be bolted on well. I also put a small notch in the bottom of the duct to make room for the heat sink grub screw.
