No. Got lucky. It's a 150qt Coleman Marine cooler at Walmart. The shelves can be found at Walmart in the bathroom storage aisle. They're called Mainstays Folding Shelf. Perfect fit in the slots and nearly as deep as the cooler. I love them. Like $5.50 each. Not to be confused with the Mainstays Short Folding Shelf or the Long Folding Shelf, neither of which would fit.
I'm thinking of taking a short one and sticking it in that pan of KL with a USB laptop fan sitting on it. Run the cord up and out the drain plug on top and to a surge prootector with a USB input. Then hook the surge protector to a timer set to run for like two minutes every half hour or hour.
Humidity is a perfect 65%, but it is a bit higher towards 68% the higher up the shelves I go. The fans would just be for mixing the humidity better, not for fresh air circulation. I open the damn thing too much to worry about stale air in there! Really happy with this setup in the few days I've had it running.
Any opinions on the fans?
