<p><strong>Stay cool during a hot day!</strong><br/> This is DIY small personal office desk cooler. I needed a cooler for my office as my pc is heating the room very fast and I did not wanted to buy a big expensive A/C. My goals for this project were to model everything with the least amount of material waste (support material) needed and that everything is easibly printable.</p> <p><strong>What you need to print:</strong></p> <ul> <li>1x air.stl, 15%-20% infill, support on built plate only (I suggest to set the overhang threshold to 10 or less --&gt; less support) If you have a Prusa MK3 you can print without any support</li> <li>1x wall, 15% infill, no support</li> <li>2x holder.stl, 15% infill, no support</li> <li>1x door_hot.stl, 15% infill, no support</li> <li><p>1x door_cold.stl, 15% infill, support on built plate only<br/> <strong>What you need for the whole project:</strong></p> </li> <li><p>1x 140mm fan (I had an old Noctua fan lying around, however any other should do the job as well) (https://www.amazon.com/Premium-Quality-Technology-NF-A14-PWM/dp/B00CP6QLY6)</p> </li> <li>4x 40x40x20 heatsinks (<a href="https://www.banggood.com/40x40x20mm-Aluminum-Heat-Sink-Heatsink-For-CPU-LED-Power-Cooling-p-1146518.html?rmmds=search&amp;cur_warehouse=CN">https://www.banggood.com/40x40x20mm-Aluminum-Heat-Sink-Heatsink-For-CPU-LED-Power-Cooling-p-1146518.html?rmmds=search&amp;cur\_warehouse=CN</a>)</li> <li>2x 40x40x20 fans (<a href="https://www.conrad.ch/de/sunon-eb40201s2-000u-999-axialluefter-12-vdc-1308-mh-l-x-b-x-h-40-x-40-x-20-mm-183786.html?insert=UP&amp;utm_source=google-shopping-de&amp;utm_medium=search&amp;utm_campaign=shopping-online-de&amp;utm_content=shopping-ad_cpc&amp;WT.srch=1&amp;gclid=CjwKCAjw8ajcBRBSEiwAsSky_dYECoYiJZuSFD6bsSRlwpCoavHhqQ9ijatys5uAed4437DHjaVgzhoCNDAQAvD_BwE">https://www.conrad.ch/de/sunon-eb40201s2-000u-999-axialluefter-12-vdc-1308-mh-l-x-b-x-h-40-x-40-x-20-mm-183786.html?insert=UP&amp;utm\_source=google-shopping-de&amp;utm\_medium=search&amp;utm\_campaign=shopping-online-de&amp;utm\_content=shopping-ad\_cpc&amp;WT.srch=1&amp;gclid=CjwKCAjw8ajcBRBSEiwAsSky\_dYECoYiJZuSFD6bsSRlwpCoavHhqQ9ijatys5uAed4437DHjaVgzhoCNDAQAvD\_BwE</a>)</li> <li>2x peltier modules (<a href="https://www.banggood.com/TEC1-12706-40x40mm-Thermoelectric-Cooler-Peltier-Plate-Module-12V-60W-p-74295.html?utm_source=google&amp;utm_medium=cpc_elc&amp;utm_campaign=ds-diy-mbz0-rm1&amp;utm_content=mandy&amp;gclid=CjwKCAjw8ajcBRBSEiwAsSky_ez-mncAgidBe-f_q4wIjPXQNfCMaDX4-9y8pC7Sn0kM-ecCospAZRoC0JwQAvD_BwE">https://www.banggood.com/TEC1-12706-40x40mm-Thermoelectric-Cooler-Peltier-Plate-Module-12V-60W-p-74295.html?utm\_source=google&amp;utm\_medium=cpc\_elc&amp;utm\_campaign=ds-diy-mbz0-rm1&amp;utm\_content=mandy&amp;gclid=CjwKCAjw8ajcBRBSEiwAsSky\_ez-mncAgidBe-f\_q4wIjPXQNfCMaDX4-9y8pC7Sn0kM-ecCospAZRoC0JwQAvD\_BwE</a>)</li> <li>4x M8 hexagon head bolts 80mm and nuts</li> <li>some 2.9mm brass tubing to mount the doors</li> <li>some little screws to mount the fans on the heatsink</li> <li>some hot glue to fix everything in place</li> <li><p>a 12V 6-8A PSU<br/> I suggest not going higher than 6-8A as the fans will no longer be able to transfer the produced heat. The cooler will no longer cool as the peltiers are getting to hot.<br/> If you want you could also 3d print the screws and bolts.</p> <p>I am soon publishing an evaporative cooling approach with much less heat output.</p> <p>UPDATE<br/> I improved the doors so now the close completely.</p> </li> </ul> <h3>Print instructions</h3><h3>Category: Office Print Settings</h3> <p><strong>Printer Brand:</strong> Prusa</p> <p><strong>Printer:</strong> <a href="http://amzn.to/2rqZ6Uo">i3 MK3</a></p> <p><strong>Rafts:</strong> No</p> <p><strong>Supports:</strong> No</p>
