Credits:
First I have to give credits to Ifixit for the idea of the fume extraxtion device. They made a tutorial and listed up all the components you need and how to wire them. So check their article if you want another explanation
Components:
- 140mm 12V pc fan
- 9V battery block + connector for easy battery switch
- 21mm diameter switch
- ribbon cables + dupont connectors
- 2 or 4 M4 screws (10-25mm)
- activated carbon filters (13x13x1cm)
Components I used (not afilliated):
Printing:
All components are correctly oriented and can be printed with your normal slicer settings except for the fan duct are tree supports needed at the overhangs.
Models are designed for 0.4mm Nozzle and 2 walls.
Build up and Wiring:
Wiring the fume extractor is simple with the correct equipment. Solder one cable from the battery to switch and connect the other cable from the battery and the other side of the switch with a dupont connector to the pc fan.
Remember that you connect the fan with the correct polarity (see last pic, ground should be the most outward port on the side from the plastic strip)
If you're using the rigth sized switched they can be inserted with a bit of force from the front side (soldering the cables first to the switch is easier but not nessesarry).
Mount the fan with 4 or 2 screws to the lid and the other side of the van to the fan duct. I used the fan included screws which have a diameter of around 5mm. Using 2 screws on the both sides of the fan are enough and 4 aren't neccesary. The fan should blow the air through the lid and suck through the fan duct. In the last step you can insert the filter and the fan combi in the case and screw the lid to the case with m4 screws.
I glued the battery in the case with double sided adhesive tape.
Finished: Enjoy you're new Fume Extractor and never inhale toxic fumes again. But also with you fume extractor you shouldn't forget to only solder in a well ventilated area.
