Hollow Object Creator is an add-on that automates the process of hollowing out solid 3D models in Blender. It allows users to quickly convert base meshes into containers, pipes, and enclosures without manual boolean operations or complex polygon editing techniques. The tool includes adjustable parameters for wall thickness to ensure precise geometry control.

In addition to general hollowing, the add-on provides options to generate open cutouts along any combination of the six primary bounding box directions (positive and negative X, Y, and Z axes). This allows for the rapid creation of open-top boxes, cylinders, and complex hollowed structures. The tool can be accessed through the Object menu or triggered using a dedicated keyboard shortcut.
