PC fan drying box. I'm not sure where I got any of the power sources, but i bet radio shack or best buy would have one. there are three wires on the fan, you only need to find the positive and neg, snip the other one and wire the fan strait to the wires. be sure to note the direction of the fan before hooking it up. mine is screwed directly to a rain drainage fitting which is seated in a 3 in PVC coupling which a storm drain cap fits right to. the fittings are only snugged together for easy maintenance. window screen was cut to shape and glued over the storm fittings to prevent active charcoal from falling through.
the carbon filter assembly was attached to the rubbermaid tub at the top using the fan screws and then sealed with duct tape.
two 3x1 inch holes were cut in the walls of the tub at the bottom to allow air to come in, these were covered with screen.
the drying racks themselves were just screens stretched on a frame, i added screws to the bottom of the racks to add height, they just stack inside the tub, make sure to make the frames too wide to hit the bottom and not too big to stack inside.
