During a scheduled super nothing to do with me meeting today I decided on some art’s n craft’s,

What we have here is a single piece, high fibre, ceral box, neatly folded and glued in place, fan secured with 4 M3 nuts and bolts. Fan is a 24v recycled from a cheap and broken inverter/arc welder.

I’ll be running the fan on 12v, and lining the bottom edges with tin foil to protect the cardboard from the heat of the portable oil heater, the idea being that moving some air over said oil heater should keep my shed/office more evenly warm.
