Description

I needed a fan for managing soldering fumes, so I made this. I used a 120x25mm computer fan (it was in my spares, I believe it was from an old ATX power supply), and a micro USB breakout board.

To assemble it as per the photo, you will need 8x M3 heat inserts, 8x M3x10 hex head screws (or similar M3 variant), at least 2x M4x30 hex head bolts and nuts (to mount the fan to the feet - I used 4x, as I have a grill on the fan from a long lost fan grill STL).

Has a small tray at the front for loose parts, two rectangle openings in the lid at the back for small slide switches (6x10mm), and an opening for the micro USB breakout board at the rear.

Hopefully someone finds this useful!
