Pumice Brick (Porous Structure)

⚠️ Note: Use at your own risk!

This is a 3D-printed pumice block designed for versatile household and hobbyist use. Thanks to its porous, irregular structure, it mimics the texture and function of natural pumice stone, making it a great tool for both personal care and cleaning applications.

The model works well as a skin exfoliator – ideal for removing dry or dead skin from feet, hands, or elbows. It’s also useful around the house for scrubbing surfaces like sinks, tiles, or stovetops without damaging them. Additionally, it can serve as a lightweight bio-filtration block in aquariums or ponds, thanks to its high surface area – perfect for growing beneficial bacteria and maintaining water quality.

The model is optimized for easy 3D printing without supports. It prints as one solid, durable piece while still retaining a sponge-like appearance and flexibility due to its layered infill pattern. You can scale it up or down based on your needs. We recommend printing in PETG or similar material if you plan to use it in water.
