evaporation (swamp) cooler

this uses the evaporation of water to cool the air. you need four feet, two saddle,a right and left shelf for the fan, four tees to hold the water tray, and an overflow drain. I used 1" pcv pipe, 34mm od and a two inch pipe, 60mm od, for the spreader bar. You will need two pipe caps for the spreader bar, a tray for the water which i got from a garden center and a aquarium pump. Drill 3mm holes on the bottom of the spreader bar for the water to drip through and make sure you install the overflow,about halfway up on the spreader bar. I ran a piece of old garden hose from the pump into the bar.
I do not blow through the material, curtain shear cloth, as it is not porous enough but it would work even better if you did have the right material. It still uses about 2 litres of water a day and cools really well. make sure the pipe you use fits through the holes before printing too far so you don't waste time and money.
