Description
This is a heat exchanger for 6in ducting.
As an example, I used it to temper incoming makeup air for a basement kitchen hood's exhaust.
I printed using carbon fiber reinforced PLA. I don't have the equipment or knowledge to test the efficiency, but feel free to experiment!

Optionally, there is a bracket included for a 140mm computer fan for cross intake, as well as a tube section to attach the intake for other ducting.
An electrical box is included that may be zip-tied to the 90° intake tube, to house AC/DC converters and voltage adapters if needed for the fan.
In the box I used a QINIZX 1N4007 AC-DC Full Bridge Rectifier, and a GYVRM 24-12v step-down converter to power the 140mm intake fan, from a standard 24vac transformer.
