Description
- Dual 80mm fan smoke extractor and filter - Designed to fit around the vertical post on a stereo microscope https://www.aliexpress.com/item/3-5X-7X-45X-90X-Simul-Focal-Soldering-IC-repair-Trinocular-stereo-microscope-With-big-boom/32911809554.html - Also uses activated carbon filters https://www.aliexpress.com/item/2pcs-lot-Activated-Carbon-Filter-Sponge-for-Hakko-493-Solder-Smoke-Absorber-ESD-Fume-Extractor-13cm/32712020268.html - Requires: 4to8* M4x25mm hex head bolts 4to9* M4 square nuts 4* M3x30mm whatever head bolts 4* M3 square nuts 2* 2sheets of 130x130x10mm activated charcoal foam filters (both cut into quarters) 2* 80nn fans - You actually need longer M4's for an 8015 than you do for an 8025, because on 9025 an M4x16mm will fit between the two faces of the fan and you can get away with just bolting through the inner face and not all the way through the entire fan. - Depending on how close to your smoke source the inlet is a 8015 is too weak for use with 4 layers of filter, go for the biggest, highest pressure 80mm fan you can get your hands on, or use less filter layers. - Note: I forgot to print orient FRAME and FANCAP... do that before printing. I almost always 'skin over' holes at some point in order to prevent support generation. It's a single layer at 0.2mm so just punch through it with a drill bit and try to get all of the debris out afterwards. - Works for me: PLA, 0.4mm nozzle, 0.2mm layers, 0.8mm walls/top/bottom, 10% grid infill, as always I suggest specifying 0.4mm external perimeter toolpath width in your slicer... but tolerances in this thing are pretty forgiving; so it may not matter. NO SUPPORTS - Update: - I'm using 2* 12V 0.5A 8025 (beefy) fans with mine now, and only two layers of filter each. Otherwise fumes manage to escape. In retrospect I should have gone for a much larger front surface area.... like the 130mm of the actual filters..... maybe next design iteration... if it fits under my microscope. - Am also using *__fanGuard-Louvred* instead of *__fanCap*
