Hi everyone,

This is an older design I created for a Prusa competition, now ported to this platform to make it more accessible. I designed this model to promote sustainability and to prove that living more ecologically is possible even in small flats or without fancy equipment. It’s a 3D-printable vermicomposter or regular composter designed with maximum compatibility and compact functionality in mind.

Printing Details

• Almost* No supports needed: All parts are designed to be support-free for easier printing.

• Material recommendation: PETG is preferred for durability and resistance to moisture, but I’ve seen PLA work well in similar designs.

• If the slanted reservoir isn’t watertight, consider coating it with epoxy resin for added protection.

*add some for the leg slots

Key Components

1. Slanted Bottom Reservoir:

• Captures liquid from the compost (a.k.a. compost tea) that can be used to water houseplants.

• If you’re unsure of your print’s waterproofing, coat the interior with epoxy or similar sealants.

2. Compost Bin:

• The main box for food scraps and biowaste.

• For vermicomposting, I recommend printing two bins with holes in the bottom. This allows the worms to migrate between bins.

3. Lid:

• Keeps odours contained and prevents unwanted pests from getting in.

4. Plug Options:

• Use the printable plug included in the files, or opt for a standard water dispenser faucet (12mm thread). For either option, use a 12-16mm gasket to prevent leakage.

5. Legs:

• Slide them into place to keep the slanted reservoir level. Plus, they add a nice visual touch to the design!

Optional Add-Ons

• Larger compost bin sizes for increased volume.

• Ventless options for those who prefer a sealed design.

This model is perfect for indoor vermicomposting or small-scale composting in limited spaces. Whether you’re already familiar with composting or just starting out, this design makes it easy to turn food scraps into valuable compost while helping the environment.

Thank you for checking out my model! Let’s work together, step by step, to live more sustainably and make the world a better place.
