<b>Stay Cool During a Hot Day!</b> This DIY small personal office desk cooler is perfect for anyone who wants to keep their workspace cool without breaking the bank. I needed a cooler for my office because my PC was heating up the room fast, and I didn't want to spend a fortune on a big expensive A/C. My goals for this project were to minimize material waste and make everything easy to print. <b>What You Need to Print:</b> * 1x air.stl, 15-20% infill, support on built plate only (set overhang threshold to 10 or less for less support) * 1x wall, 15% infill, no support * 2x holder.stl, 15% infill, no support * 1x door_hot.stl, 15% infill, no support * 1x door_cold.stl, 15% infill, support on built plate only <b>What You Need for the Whole Project:</b> * 1x 140mm fan (any old Noctua fan will do the job) * 4x 40x40x20 heatsinks * 2x 40x40x20 fans * 2x peltier modules * 4x M8 hexagon head bolts 80mm and nuts * some 2.9mm brass tubing to mount the doors * some little screws to mount the fans on the heatsink * some hot glue to fix everything in place * a 12V 6-8A PSU Don't go over 6-8A, or the fans won't be able to transfer heat properly. The peltiers will get too hot, and the cooler won't work as well. You can also 3D print the screws and bolts if you want. I'm soon publishing an evaporative cooling approach that produces much less heat output. <b>UPDATE</b> I've improved the doors so they close completely now!
