CO2 Diffuser for Planted Tank

I started using DIY CO2 in one of my tanks thats growing out plants for other tanks and I needed a diffuser. I know the glass ones are cheap, but this was next to free and I have no patience to wait for shipping.

This model makes use of the ability to modify specific object parameters in the slicer. I found that 7% infill for the body is sufficient to not hinder the flow but provide enough structure for the grid plate. Similarly, I've found that 80% infill for the grid is making good micro bubbles for the CO2. If you wanted to use this as an air stone, I'd recommend a more coarse grid. Maybe around 60-70% infill grid.

Cannot have any top or bottom layers for “Infill” and “Grid” otherwise it won't work correctly.

Wall loops not needed for “Infill”, Optional for “Grid”.
