Baby proof and nice to look at
I spent way too much on this.. was a fun project tho!
I added an ESP32 device to control it with Home Assistant.
Also, lesson learned, don’t touch a running fan to figure out if it’s getting hot when it’s running full speed
Edit:
Here are some additional details.
For Next time - Adjust overall width to 19.75". The filter is very snug, I forgot to add a bit of room for play.

Wiring Instructions:
If you want the fans to just run at 100% without controlling remotely, exclude the USB-C Converter and ESP32 device. Mine ran fine like this constantly powered on for several days, was just a big loud for my liking. I run at 60% now.
