Made from a perforated cylindrical container, this bin allows worms to move freely between the surrounding soil and the scraps inside, turning waste into nutrient-rich castings right where your plants need it. Material: I recomment to not print this in PLA as it is less resistant for outdoor use but rather use PETG. Installation Instructions Choose a Location Place the bin in a garden bed, preferably near plants that can benefit from the nutrient-rich soil. Pick a shaded or partially shaded area to prevent overheating. Dig a Hole Dig a hole to bury the cylinder. Insert the Bin Place the cylinder in the hole, ensuring it's upright and stable. Fill the soil back around the cylinder to secure it in place. Add Bedding Add a 3–4 inch (7–10 cm) layer of moist bedding inside such as wet soil. This creates a comfortable environment for the worms. Introduce Worms Add 250–500 composting worms (e.g., Eisenia fetida, also known as red wigglers). Cover lightly with food scraps and more bedding. Usage Instructions Feeding the Worms Add food scraps 2–3 times per week. Ideal items include: Fruit and vegetable peels Coffee grounds Crushed eggshells Shredded paper or egg cardboard Avoid: meat, dairy, oily foods, citrus, spicy items, and large volumes of onion or garlic. Cover and Moisture Cover food scraps with a layer of bedding or soil to reduce odor and fruit flies. Check moisture: bedding should feel like a wrung-out sponge. Add water (rarely needed) or dry bedding as needed. Harvesting Worm castings will accumulate at the bottom over 2–3 months. You can remove the top food layer, scoop out finished compost from the bottom with a hand trowel, then return the rest. Alternatively, install multiple towers and let one rest while harvesting from the other. Maintenance Tips Check the bin weekly for moisture and food levels. If ants or pests appear, reduce food quantity and add more bedding. Troubleshooting Issue Cause Solution Bad odor Too much food, not enough bedding Add dry bedding, mix contents gently Worms escaping Too wet, too dry, poor food Balance moisture, avoid acidic/spicy foods Mold or fruit flies Exposed scraps Cover all food with bedding
