The fan setup itself is described in more detail in this blog post. I place this fan under a stand for and behind an Elecraft KX3 radio, powered by a ~12VDC source, quietly blowing air over the (3rd party) heatsink for high-duty cycle modes like FT-8. This keeps the temperatures down always and takes the edge of the thermal load on the radio. It's nothing fancy but functional, slips on and off as needed, and can go into anyone's go bag.
I wanted it to be a little bit more stable for placing on uneven surfaces like a picnic tables without adding lots of bulk. I made this minimalist stand for a Noctua fan (80x80x25, but it will fit other Noctua x25 fans), which friction fits on the silicone vibration isolators (slight interference fit) at each corner of a Noctua fan next to the mounting holes.
I printed these parts with brim in 0.2mm LH from PolyLite ASA Army Brown; not a perfect match for Noctua's dark brown, but close enough for me.
IMPORTANT: Ensure you have corrected your filament settings for shrinkage. Print a 10x10x20 primitive, measure, and add a parameter to the filament settings for shrinkage. For example, if a side is 9.8mm instead of 10mm, your shrinkage should say 98% for dimensional accuracy. Reprint and double check.
PS: The fan also works great to dry the sweat off your fist or forehead. ;-)
