"Inspired by" the Hakko FA-400, this is a solder fume extractor designed to be used either horizontally for greater suction speed or verically for greater suction volume. In the .stl files attached, it is configured to use a 120mm fan and the 130mm by 130mm carbon filter that goes with the actual Hakko extractor and its various knockoffs. The filters for the Weller benchtop fume extractor should also fit. The .scad file is parametric, so changing to a different sized fan or filter should just be a matter of changing a few numbers.


  1. Adjust the .scad file to fit a different sized fan or filter if you don't want to use a 120mm fan with a 130mm filter.
  2. Print out the fume_extractor.stl
  3. Optional: Print out the filter_holder.stl if the filter is loose. I found that it fit in snugly without the holder, but if the filter is falling out, you can use one.
  4. Optional: Print out a fan grill for the other side of the fan. Here is the one I made for my 120mm fan: http://www.thingiverse.com/thing:17028
  5. Screw the fan into the extractor with fan screws if you have them of 1/2" #6 bolts if you don't.
  6. Insert the filter, and optionally slide the holder in over it.
  7. Power the fan. I used a 12v wall wart that I had left over from something else.

Thanks dude! I used the SCAD file to remix it a bit to add holes for routing wires, a fan speed controller and a DC battel plug. Works beautifully!

I have yet to make this, but i figured i would mention that amazon (and im assuming other sites) sells cut to fit carbon filters, probably for much cheaper than the precut company ones. Also makes scaling this up or down less of a issue.

no filter, quiet useless

Printing today. Great idea - thanks for sharing!

Made one today - works great, thanks...

This is really a smart design and saves me the trouble of designing something that's worse. thanks!

Printing at 78% works perfectly for a 92mm fan!
Thank you for the design!

If I try scaling at 78% , slic3r fills in above the vented area. How were you able to use this file?

Thanks for sharing your design. The holes aligned perfectly as well as the screw hole sizes. Works great!

Any plans for a 70mm fan? thx

Thanks for the design, and especially for including the scad file. I had to make the walls thicker for my printer to do a good job.

I made one and velcro'd a RC LiPo battery to it, works great!

Thanks for the design.

This is awesome, but a little oversized for many printers. Any way you could split the original design files into a half that could be printed twice on a smaller build platform? Would be easy to reassemble into a whole piece once mounted on the fan with the screws.
