This is for those who don't often use the magnifying attachment on their helping hand and are in need of a fume extractor.
Use wood screws that are about 3.5mm in diameter and about 18mm long to secure the fan. The inlet should meet with the 'top' of the printed piece.
Cut a 65mm square out of any activated carbon filter. Secure it to the 'bottom' of the piece using one rubber band looped through all four "U" tabs.
Pull out the magnifying glass on helping hand tool and slide the new assembly into place.
- Run power leads as desired.
