Vermicomposter from IKEA

Start your own earthworm business with just a few simple tools: couple boxes from IKEA, a drill, and some hooks from 3D printers. The key to success lies in getting the sizes and number of holes just right. Here's how it works: First, place a box at ground level without any holes - this will serve as a water reservoir, providing perfect fertilizer for your worms. Next, add a second box with 3-5mm holes drilled into its bottom; these holes allow moisture to escape while keeping the material and worms safely inside. Finally, use the last two boxes, drilling 10mm holes all over them to ensure sufficient airflow, facilitate worm tunneling, and slow down the movement of materials down the system. Hooks printed from PLA provide outdoor durability and UV stability, allowing you to hang your setup with confidence.
