Water trap for use with aquarium tubing. It collects liquid water and prevents small amounts from flowing down the tube. I'm using it with a reversed aquarium air pump (reversed to generate suction instead of pumping air), the side with the inside tube connects to the vacuum pump.

The wall thickness is 1mm, but its slightly thicker (in the X-Y axis) where the walls are angled so I printed it with an approximately 0.55mm extrusion width.
