Aquarium Decoration - Textured Rock Cave - Large Tented

thingiverse

Custom Rock Shaped Cave with Two Entries for Fish, Shrimp, or Reptiles. ~25cm X ~21cm X ~14cm. I'm a big fan of textured rock caves - my fish just love them! If you're not keen on the holes, I've included a version without for aquascaping or adding your own decorations. This design features 2mm walls and is intended to be printed with 100% infill and no supports. Due to thin walls, significant resizing (anything over 50%) may not work. PLA and PETG plastics are denser than freshwater, so a 100% infill will naturally sink to the bottom of your tank. On safety and longevity: Both PLA and PETG plastics are generally considered food safe, but some dyes and additives might not be. I use natural colors to play it safe. The decorations are painted with non-toxic acrylics and coated with plasti-dip (also generally considered aquarium-safe) to seal the paint. I recommend printing in PETG long-term since PLA is biodegradable and will break down when exposed to heat and water, although it's said to last over a year. Disclaimer: I'm just a hobbyist, so everything I've said is based on my personal experience and what I've read online. It's always best to do your own research and consult professionals whenever possible.
