Free 3D model search engine, designed for 3D printers. On Lagoon.io, you can find 3D models of kind. All files are in STL format, and are able to be sliced and 3D printed. We are currently sourcing our models from Thingiverse and related sites, but want to expand further to user uploaded content. Lagoon.io includes an optional 3D printing service where we 3D print the items for you, and handle all the logistics.
