Solder Fume Extractor

Update 8/2/17: Thickened the parts for the shrouded setup in hopes of making it a little more robust. I have not printed the parts but they look okay in CAD. I also modified the hardware used on the thicker parts to take advantage of easier to find M4x50mm screws. Just sub in the (3) thickened parts as needed.

Update 4/21/16: Modified base option added that provides a slight tilt to the whole assembly as seen in the first pic.

I couldn't justify paying $60 for an off-the-shelf fume extractor so I designed this for use while soldering or dealing with other unwanted vapors. The fan is a standard 12V 120mm case fan and the filter is 130mm x 130mm x 10mm (link in parts section). It also employs an on/off switch and power jack.

There are a couple of configuration options:

• The rear vent is optional; if you plan to install it, print out the base designed for the vent (base_for_vent.stl). If you think you might want to add the vent later, go ahead and print the base for the vent, it will be perfectly functional without the vent installed.
• There is a flat front panel as well as a shrouded front panel.

There is an additional tilted base option available that will tilt the shroud at a 20 deg angle. Additional Parts Needed
(1) 120mm 12V case fan
(1) 130mm x130mm x 10mm carbon filter (http://www.amazon.com/Carbon-Filter-Activated-Xytronic-Absorber/dp/B005C5HUI8 or equiv.)
(1) Rocker switch (Philmore p/n 30-16705 or equiv.)
(1) DC power jack 2.1mm x 5.5mm (Philmore p/n 247 or equiv.)
(1) 12V power adapter (http://www.amazon.com/KCRIUS-Power-Adapter-Supply-2-1mm/dp/B00KG3A25Y or equiv.) Note that the recommended adapter has a fairly short cord, if you need something longer feel free to substitute.
(4) M4 x 55mm socket head cap screws
(4) M4 nuts
(4) M4 washers (if not using rear vent)

Instructions

Print the following parts:

• Hood_A
• Hood_B OR Hood_B_with_shroud
• Base OR Base_for_Vent OR Tilted_Base_for_Vent
• Rear_Vent (Optional)

If using the rear vent, install the nuts into the reliefs in the back of the mounting tabs.

1. Wire up the fan, switch and power jack.
2. Secure the switch and power jack into the base.
3. Run the screws through Hood_A, the base and the fan.
4. a. If using the vent, install now and use embedded nuts to secure everything together.
   b. If not using the vent, install the washers and nuts directly onto the screws, securing everything together.
5. Carefully clip Hood_B/Hood_B_with_Shroud to Hood_A.
6. Install carbon filter in the cavity created by the two hood pieces.
7. Breathe easy.

Supports are probably only required for the rear vent; that said, I used them on some of the other parts so as to not have to worry about bridging issues.
