Built-in Themes¶
Built-in themes are pre-designed themes that provide a quick and easy way to customize the look and feel of Mainsail without creating a design from scratch.
Mainsail includes themes from two groups:
- Open-Source Communities: Themes from large open-source 3D printing projects
- Vendor Sponsors: Exclusive themes as recognition for their support
