16cm carbon filter for soldering fumes for 14cm fan

a carbon filter. if you want to remix it for another sized fan, that's cool. otherwise can resize.

glue a square of fine netting/old t-shirt 16cm^2 inside of tray and base of top, using a bit of acetone, fill with carbon, glue the base to the top with acetone, and bolt onto a 14cm fan. should last 2-3 years.
