Surplus Current Available at Fan Port of Enclosure Converter?

Well, assembly in place, fan tested. First laser test to see if this gives me enough filtration later today. (Obviously I can still pack rather a bit more in the tupperware…)

I could feel good airflow into the rear port from the Snap’s own fan, just testing with the lid off before putting in anything, and obviously the front exhaust fan I added was easy to test even after…
