Fume extractor with common 120mm computer fan

prusaprinters

<p>We didn't bring our fume extractor. And it take a long time for us to consider what is suitable for the workbench. Since it still need to take more time to select a nice commercial one. How about just build one for minimum requirement for current need with the materials I can find in our office. So it comes out this one is not too bad. It can extract the fume within 5~10cm.&nbsp;</p><p>&nbsp;</p><p>parts&nbsp;</p><ol><li>120mm X 120 mm 12V PC cooler fan (we just have extra one in office)</li><li>screw nuts and M3 screws for assemble</li><li>led strips for working, I mount the 5v led strip and it is ok. but later I just solder some 3528 warm white leds plus resistors on the perfboard and adjust its power input to meet the same 12V DC power.</li><li>12 DC power supply (if I have time, I can try to dig the unsorted components bags to find the dc/dc boost chips to build a board to boost 5V to 12V in the future. )</li><li>carbon filter (I use the one I got in the DIY market which is 1mm thickness big sheet, and I cut them in to 2 pieces to make it thicker for the filter)</li></ol><p>3d printing parts</p><p>1 pc fan frame.stl -- required</p><p>1 pc filter spacer.stl --required</p><p>1pc fan stand (R)--required</p><p>1pc fan stand (L)--required</p><p>1pc stand bottom(Bot) --required</p><p>&nbsp;</p><p>1pc led strip holder-R --optional, if you don't need to mount the led, can skip it</p><p>1pc led strip holder-L &nbsp;--optional, if you don't need to mount the led, can skip it</p><p>some cable holders--optional, if you don't need to hold the cables, can skip it. it is a little too small for my fan, so i skip it.
