Soldering Fume Extractor/Absorber

I was looking for a commercial fume extractor but saw the price tag. So I searched for a DIY thing here at Thingiverse and found the fume extractors linked as remix sources. Though being nice, I thought of something more "complete," something with an on-off switch, something that one can quickly detach from a power supply.

So this is the design I made from scratch.

It features a switch on top with an LED indicator, has a metal fan grille on the back for safety reasons and a printed clip-in grille at the front to secure the activated carbon filter in place. Furthermore, it is a larger design: The 80mm 12V fan provides power to suck in all the bad things coming from the solder.

Please also take a look at the print settings and post-processing section for more details.

Some video footage of this fume absorber can be found at YouTube:

Print instructions

• Printers used for this project: Prusa Research and MendelMax3 from Maker's Tool Works

• Supports: Not mandatory - depends on how well your printer can handle overhangs!
• Resolution: 0.20 mm
• Infill: 10% to 20%

Notes

I printed the body and the grille using a 0.4mm nozzle and 0.2mm layer height. There should be no infill needed for the body's walls. Just use enough perimeters. I used four. For the stand, I used a 20% rectangular infill, but much less should be also good enough to provide a sturdy build.

The switch has a necessary hole diameter of 2.1mm and so has the 3D model. If you want to use a switch with another diameter, please let me know in the comment section.
