Duplicate Finder and Remover is a Blender add-on that finds, reviews, and removes duplicate or overlapping mesh objects in a scene. It scans selected, visible, or all objects and groups results in the 3D Viewport sidebar.

Hole Remover is a Blender add-on that detects and removes circular through-holes in imported CAD meshes. It reduces polygon count to support easier editing, faster rendering, and real-time 3D workflows.
