Air Stone for Aquarium or Hydroponics

<p>I made this Airstone. It works by altering small arcs, thus creating little holes. I used some 2 cent coins to weigh it down enough so it will sink to the bottom. However, you may get away with printing it at 100 % infill, as both PLA and PETG are denser than water (I did not test this though).&nbsp;</p><p>I designed this with 0.6 and 0.4 mm nozzle in mind.</p><p>Layer height of 0.2 or 0.3 should both work as the arcs are 0.6 mm high.&nbsp;</p><p>If you need another size, let me know or remix it yourself :)</p>
