Hey! This thing is still a Work in Progress. Files, instructions, and other stuff might change!
Golieth Sized Reef Ball
One of Reef Ball Foundation's largest artificial reef designs. In the real world this is 6 feet tall and made of pH neutralized concrete and used to create fish habitat and coral reefs.
Not scaled, you must scale before printing to your printer size. I have not test printed this yet and it does not have a rough surface like a Real Reef Ball. This is to be used to make demonstration models not to be placed in the sea. Use must attribute copyright holder as reefball.org but you may freely print.
