Pool Filter Air Bleed Filter

This is a replacement filter that goes over a 1/4 plastic line to bleed the air out of the top of a pool filter. This filter keeps debris from entering the air bleed tubing and clogging it. Simply print out two parts, stuff some polyfill inside then glue the two pieces together with superglue. It may work on other sizes of small tubing as well. The opening is 7.8 mm and tapers down to 5.5 mm.
