NV-AA1-12 Airflow Amplifier - Trunnion Mount

I added a set of trunnions to each side of the amplifier and a stand. 

The trunnions (pivots) are close to the center of gravity of the assembly. This means the tightness of the screws isn't as important.

I used rubber washers to aid in the pivot friction.
 

I used M4X10 SHCS and matching short brass heatserts in the trunnions.

I've added the STEP file so others can easily modify the file to accommodate printed threads, or other fastener sizes.

Edit: I've added a version with mounting holes in the base (stand). This ends up slightly wider than the original.
