In-bed worm tower

Compost kitchen scraps right inside a raised bed through a worm tower

Instead of carrying compost to the plants, bring the compost to the plants. Bury the lower half of this tower in a raised bed, drop in some compost worms and feed it vegetable scraps through the lid. Worms come and go through the windows near the bottom, eating the scraps inside and leaving their rich castings out in the bed around the roots. The lid keeps flies and smells in, and one tower feeds roughly a metre of bed.

How to print it

It is 240 mm tall, so lower the height on a smaller printer. Bury the bottom half in the bed so the side windows are under the soil, add a handful of compost worms, and feed scraps through the lid.

Prints as shown on its floor, no supports. Large holes in the walls may need supports or good bridging. The lid prints as a separate part, top down.

Filament: at most about 283 g of PLA printed solid (roughly $5.66 at $20 per kg); normal infill uses less.

To get the files, open it in the generator and choose File › Download STL (one file per part) or Download 3MF (every part on one plate).
