These are 3D-printed stopper plugs designed specifically for a tumbling composter with a 70-liter capacity. The primary purpose of these plugs is to seal the pre-existing holes in the composter. By doing so, they prevent small debris from leaking out when the composter is rotated. The plugs are inserted from the inside, ensuring a tight seal that maintains the integrity and cleanliness of the composting process.

…hWhile these 3D-printed stopper plugs seal the holes, some debris and colored water can still leak from other gaps, especially when exposed to rain.
