Mossy Bubbler - Fully printable Spongefilter with Voronoi Mossholder

thingiverse

This Sponge Filter employs standard Air tubes and a cylindrical 2.5cm / 1" long and 1.5cm wide Air stone. **How to Print:** Only use high-quality Aquarium-safe Filament and Colors: for instance - PLA - Natural/Transparent - the more reputable the manufacturer, the better, also refrain from using recycled filament. Both files must be printed on top of each other: 01_MossyBubbler - 100% Infill with Perimeters 02a_SpongeFilter - 25-80% Gyroid Infill pattern without Perimeters // 01 is not cut out from 02a because I encountered slicer issues, if I can resolve that problem, the file will be 02b, for now some parts are printed twice, with a 50% Infill for 02 which wasn't a challenge. **How to Slice:** In Slic3r: 1) Load 01 2) Right-click on 01 and navigate to settings 3) Load 02, now both files are stacked on top of each other 4) Select the correct settings for each Model 4a) Slic3r sometimes prevents printing without Perimeters; choose Perimeters and Bottom Perimeters 0 and Top Perimeters 1. I also applied a -20% Infill/Perimeter Overlap. ++ There is often a Fuzzy Skin modifier in some slicers, which could be beneficial to use here (increased surface area) ++ **How to Assemble:** The Tube feeds through the top, and the stone passes through the bottom. Moss strands can be attached on the Voronoi pattern. Either bury the rim in Gravel or place a stone on top; with air, it tends to float. **How It Should Work:** The Gyroid infill is similar to open-cell foam and should provide an abundance of surface area. If you have the Fuzzy Skin modifier, even more so. On that surface, Bacteria can grow that convert Nitrit into Nitrat. The Moss utilizes and binds the Nitrat. The Air bubble provides an updraft which draws in water and oxygenates it simultaneously. **How It Works:** Only time will tell... ++ Future updates hopefully include the slicable 02b model, a printable Airstone, and a bottom cover with suction cup attachment.
