Aquarium Decoration - Textured Rock Cave - Large B

thingiverse

Custom Rock shaped cave with two openings for fish, shrimp or reptiles measuring 25cm X 21cm X 15.6cm. This release includes a version both with and without holes, offering a more natural look for aquascaping. The version with holes was designed to accommodate large fish, such as a Frontosa that outgrew the other rocks, featuring a large ~12cm tall hole for large fish and a small side hole allowing small fish to escape. Crafted with 2mm walls, this design is intended to be printed with 100% infill and no supports; thin walls make it unsuitable for significant resizing, but a 50% change should work. PLA and PETG are both denser than freshwater, so 100% infill will naturally sink to the bottom of the tank. Regarding safety and longevity: Both PLA and PETG plastics are generally considered food safe, but some dyes and additives may not be, so I use "natural" color to ensure safety. The decorations are painted with non-toxic acrylics and coated with plasti-dip, which is also generally considered aquarium safe, to seal the paint. I recommend printing in PETG for long-term results since PLA is biodegradable and will break down due to heat and water presence, although it should last over a year according to all accounts I've read.
