Air stone - Φ15x25(120) - Internal ZigZag pattern

By request there is now a 120mm version available also.This is a simple aquarium air stone, with an internal zig zag channel. The airstone itself has a dimension of Φ15x25. I have tried quite a few iterations of the channel design, to me this yielded the seemingly best results.Important to note, that for aquarium use PETG is recommended, however from what I could find, regular PLA (without additives, or special attributes, like PLA+) could also work, except some color combinations, which could still leech into the water after some time. The optimal layer height for this print is 0,16mm.It is highly recommended to use Arachne wall generator, as it will result in a much nicer print. Here is an example of how it should look like, in case you slice it with Arachne: For me it printed without issues, however in case you run into problems, or if you have some recommendations on making this design more effective, please dont hesitate to reach out and comment.Boost MeBoost me if you like my wor
