Hydroponic/Aquarium Air Stones

Some small air stones I designed for standard air pumps commonly used in aquatic and hydroponic systems, utilizing durable 1.75m PETG material. I suggest printing them upright with the base on the print bed to achieve optimal layer adhesion. For the rectangular ones, using a raft helps ensure they adhere properly to the print bed. The rectangular air stones seem to perform exceptionally well for me, but the cylindrical ones also work effectively when tilted horizontally. You can easily secure the rectangular air stones at the bottom of the water reservoir using mounting tape or a suitable adhesive, which enables great air dispersion. I used 50% infill, but this is not strictly necessary.
