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
• 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.

PETG filament is a premium material chosen for long‑term aquarium use. Unlike PLA that can warp, soften, and break down, PETG is stable, strong, and temperature‑resistant. It offers better durability, water and chemical stability, and higher heat resistance — ideal for real, working tanks. Every item is printed at 100% infill, so it always sinks, feels sturdy, and has no pause lines from added weights. Many companies stop their prints mid‑way to drop in metal; we take the extra time to print each piece full of only filament for a cleaner finish and stronger structure. The result is décor that lasts longer, looks better, and performs reliably — built for aquarists who value quality over shortcuts.
