XMachines Lorei fan duct (easy mount)

I modified the "fan duct" design for easier installation. There are only the bottom two screw mounts left. I also wanted to get rid of the tiny hex nuts on the back so the holes are 2.6mm in diameter in the model and I used a **3mm thread cutter** to finish them off.

The two holes are tilted by 1.5° on purpose so the upper part of the duct should be pressed slightly against the fan to counter any gap.

Thanks to dulfe for the original design:
