Aquarium Decoration - Wood Textured Branching Stick Cave - Large

thingiverse

Large multiple entrance wood textured cave. 15cm X 12cm X 20.9cm in size. Designed with 2mm walls for strong structure, meant to be printed at 100% infill with no supports needed; thin walls allow for minimal re-sizing without compromising integrity (less than a 50% change should work fine). Print as designed to avoid the need for supports, leaving the bottom of the cave open to conserve filament. PLA and PETG plastics are denser than freshwater, so 100% infill will naturally sink to the bottom of the tank. On safety and longevity: Both PLA and PETG plastics are generally considered food safe, but some dyes and additives may not be safe for use in aquariums; I opt for "natural" colors as a precaution. Decorations are painted with non-toxic acrylics and sealed with plasti-dip, which is also generally considered aquarium safe, to ensure durability and safety. I recommend printing long-term with PETG since PLA is biodegradable and may break down in the presence of heat and water (although it should still last over a year).
