I've created a new mount for  Ender 3 Titan Aero as there were no dual 5015 fans models.
Current state
Public beta. Airducts and fan mount may change. The main mount itself looks to be stable, but may be changed in a case of serious issues.
Key features of my design
Rigid and steady mount for all the stuff.
No supports, easy print.
BFPTouch-slim mount included
Dual 5015 fans with vertical offset regulation
Air flow simulated design. I've included the simulation results, so you can be sure, that the printed item gets the proper cooling. Peak air velocity is about 35 m/s just below the nozzle.
It looks cool, I suppose.
Look for further instructions and updates. The project status is public beta, so all the bug reports are welcome.
I want to thank everyone for their precious advices, especially Adolf Muffin (https://www.thingiverse.com/adolf_muffin)
Known bugs
Some 5015 fans may not fit the cover because of the seams. I’ll fix it as soon as possible. (Fixed)
Bad cooling of the part's back surface. Airduct refactoring…
