Fume extractor with lights

prusaprinters

<p>Fume extractor created from an old halogen desk lamp. The halogen light is replaced with an LED strip and fumes are extracted using a re-purposed CPU fan through a filter.</p> <p>This mainly serves to stop the fumes from drifting towards me, but I added a carbon filter sponge in the hope that it will actually keep some of the nastiness out of the air in the room...</p> <p>This requires:</p> <ul> <li>Old CPU fan (the scad file expects 42mm between screws)</li> <li>Halogen desk lamp (the kind with two telescoping metal arms)</li> <li>Diode bridge (e.g. one from <a href="http://www.ebay.com/sch/i.html?_nkw=diode+rectifier+bridge+2a&amp;_sop=15&amp;LH_BIN=1">ebay</a>)</li> <li>Optionally, a toggle switch to have lights without the fan</li> <li>A carbon filter sponge, cut to size.<br/> Essentially replace the normal head of the desk lamp with this print. You will have to adapt the measurements to that of your fan and the specific desk lamp.<br/> See <a href="https://youtu.be/gUobW6_HgxE">https://youtu.be/gUobW6\_HgxE</a></li> </ul> <h3>Print instructions</h3><p>No supports, 0.2mm layer height.</p> <p>Note that the wall is thin (1.2mm), but four internal pillars make the structure itself fairly sturdy.</p>
