Built-in Themes

Built-in themes are pre-designed themes. They provide users with a quick and easy way to customize the look and feel of their interface without having to create a design from scratch.

In Mainsail, there are two groups that are permitted to have built-in themes. The first group consists of all vendor sponsors, who receive exclusive themes as a recognition of their support. The second group includes large open source communities.

If you are a maintainer of a large open-source 3d printing project, please contact the Mainsail crew on the Discord server for a built-in theme.
