Cooling fan adapter for running a line up to cool your keg taps. Keep your beer cold. This is a slightly modified file of another Thingiverse file so I cannot take much credit- only the application :) Fits a 70mm fan. UPDATE Although this did work I scrapped it in favor of a box style setup. The funnel chokes the airflow way down and causes the fan to stall far too much.Prints great on a Solidoodle. Should be no need to repair, just print.
