after a dry run last night that went really well I just filled up the 3D with a big batch of cheese. Extra sharp, sharp cheddar, Gouda, parmesan, colby, colby jack, monterey jack, pepper jack swiss, and mozzarella
. I'm using the small (6x6) amzn with cherry saw dust. I removed the drip pan, the wood box. Right on top of the drain hole I place a 80mm 24v fan sucking air from the outside, and hooked up to a 12v power supply so the fan run pretty slow. Outside temp is around 40F and after 2hrs the temp inside the 3D is steady 59F. Planning to let this go for about 4 to 5 hrs while moving the shelves about twice. here's some pics
