I would like to present my version of NV-AA1-12 Airflow Amplifier stand mount.

It's prepared for 140mm fan, I was using fans from my North PC case, I'm sure it's compatible with Arctic 140mm fan and probably with many more other fans that have cutouts. It was designed to mount between fan but also I'm providing universal mount for any 140mm fan, just crew in to front of airflow amplifier for perfect balance.

Also

It has advantage over other solutions as it uses ONLY 50-60g of filament and prints with bambu pla in less than 2h. Other solutions use over 100g and print over 4-5 hours.

attention - one screw is left and another is right threaded, if you have problem with assembly, try second screw. There are supports inside thread hole, but I easily poked it with larger screwdriver provided with printer, you can use anything to gouge through support, should came off as whole.
