This is a flowerpot and saucer with a gently curved shape and a textured appearance. The texture comes from applying a surface lattice on the surface.

You can customize the surface of your pot using this project and Metafold's web application for design. If you have a Metafold account (paid or free!) you can duplicate the project into your personal workspace and remix it. The saucer file is here.

Using Metafold's implicit modelling 3D software it was easy to design this in my web browser. Metafold has a free tier -- check it out!
