Ender 3 dual 40mm fan hot end cooling shroud with BLTouch mount
Description
I was looking for a new hotend shroud that allowed me to use two 4020 fans for the hot end and part cooling fans, had a mount for BLTouch and was not too big. I liked [Horvat208's](https://www.thingiverse.com/thing:4153402) 4020 hot end fan shroud, as well as [mrfochs'](https://www.thingiverse.com/thing:2972610) adapter to use 40mm fans for part cooling. I could have just used them straight up, but didn't feel that just screwing them together with the two bottom screws was going to be secure enough, and I didn't want to use screws to connect them. I thought about merging them into one part, but it would have made it too difficult to print. Thus the dovetail connection idea. It's a real tight fit, so make sure your printer is well calibrated. I had to use some persuasion for them to slide together. I modified the parts using Fusion360.
