partial spheres
thingiverse
This customizable tool enables you to generate partial spheres of any degree (0-360°) and radius. It was designed with BlocksCAD. It was created for a project, Moon Time, where I needed to illustrate various phases of the lunar cycle with half moons. To edit this project with BlocksCAD, download the .xml file and load it at https://www.blockscad3d.com/editor. Be cautious when printing spheres over 180°, as they can be tricky to print.
