Minimalist 3D Printed Fume Extractor

This is my build of the "Minimalist 3D Printed Fume Extractor" by rdmmkr. The case has been extended to incorporate the "'Punished' 80mm fan shield" by jd52wtf. The power socket was modified to take a DC022B DC Power Socket.

Active Carbon Filter

3D print "minimalist-3d-printed-fume-extractor_cartridge-bottom.stl" and "minimalist-3d-printed-fume-extractor_cartridge-top.stl". Use a 0.2mm layer height. Orientate the top part 180 degrees so it sits flat on the build plate. Use a contrasting color to that of the case.

You will need to cut the activated carbon foam to fit in the holder. The holder slides into the top of the case.

Fan and case

The fan used in this project is a 80mm x 80mm x 38mm 12V case fan. The one I used in this project has dual ball bearings for longevity.

3D print the "Min_Left.stl" and "Min_Right.stl" using a 0.2mm layer height. Orientate each case half so that the case's side is on the build plate. The fan shield is also printing using a 0.2mm layer height and you will need to switch to a contrasting color at the start of layer 16.

Heat press in a 5mm x 3.2mm M2 Brass Insert nut into each case half.

Also heat press in 4 off 5mm x 6mm M4 Brass Insert nuts into the fan. Make sure it is the fan side with the label.

Add wires to the DC022B DC Power Socket before glueing it into the right hand case using super glue.

My fan came with four wires. Only red and black are required so you can cut the others short. Insert the fan guard and fan in the right hand case and run the wires through the hole provided. Screw it in place using 10mm M4 screws.

Add the left hand part of the case and also screw in place using 10mm M4 screws.

Front panel

3D print the "minimalist-3d-printed-fume-extractor_lid.stl" using a 0.2mm layer height. Orientate the part so the front is on the build plate.

The front panel contains a 3mm LED, 2.2k ohm resistor and a rocker switch. The main thing to watch out for is that the LED is wired correctly otherwise it won't light up. While the wiring layout shows a 680 ohm resistor, I found the LED was too bright and changed it to a 2, 200 ohm resistor.

I also used some pin headers so that I could unplug the front panel. This is an optional step.

Screw on the front panel using 6mm M2 screws.

Conclusion

I love the result of this project. The fan grill makes it looks super cool (excuse the pun). Thanks rdmmkr for a very well thought out fan design and thanks to jd52wtf for a great fan grill. 👍👍👍
