Solder Fume Extractor

thingiverse

Update 8/2/17: Thickened the parts for the concealed setup to make it more robust. Printed parts show promise in CAD, but they haven't been printed yet. Modified hardware on thicker parts utilizes easier-to-find M4x50mm screws per canadadry's suggestion. Simply substitute (3) thickened parts as needed. Update 4/21/16: Added a modified base option that provides a slight tilt to the whole assembly, visible in the first picture. I didn't want to spend $60 on an off-the-shelf fume extractor, so I designed this for use while soldering or dealing with 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 features an on/off switch and power jack. There are several 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 fully functional without the vent installed. There's a flat front panel as well as a shrouded front panel available. Additionally, there's an optional tilted base that will tilt the shroud at a 20-degree 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 equivalent) (1) Rocker switch (Philmore p/n 30-16705 or equivalent) (1) DC power jack 2.1mm x 5.5mm (Philmore p/n 247 or equivalent) (1) 12V power adapter (http://www.amazon.com/KCRIUS-Power-Adapter-Supply-2-1mm/dp/B00KG3A25Y or equivalent) 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. If using the rear vent, install the nuts into the reliefs in the back of the mounting tabs. Wire up the fan, switch and power jack. Secure the switch and power jack into the base. Run the screws through Hood_A, the base and the fan. 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. Carefully clip Hood_B/Hood_B_with_shroud to Hood_A. Install carbon filter in the cavity created by the two hood pieces. Breathe easy. Print Settings: Printer Brand: RepRap Printer: Makerfarm 12 Rafts: No Supports: Yes Resolution: Printed at .25mm height with a .4mm nozzle Infill: 25%, 1mm thick top and bottom layers Notes: Printed in ABS. Supports are probably only required for the rear vent; I used them on some of the other parts to avoid bridging issues.
