Marrow Log

The core of something ancient.

The Marrow Log is a 3D-printed aquarium decoration inspired by the hollowed-out interior of aged, waterlogged wood — the kind of piece that looks like it's been slowly claimed by the riverbed over decades. A dense Voronoi lattice of organic openings wraps the cylindrical form, creating a rich, textured surface that shrimp, nano fish, and invertebrates will explore endlessly.

Details:

• Material: PETG filament — aquarium-safe, durable, and warp-resistant
• Dimensions: 4" long × 2" wide × 2" tall
• Best for: Shrimp tanks, nano tanks, and planted tanks.

No soaking, no tannins, no pH surprises — just drop it in and watch your tank come alive.
