3D File Toolkit — Development skill for Claude Code

Development community

Pure-Python toolkit for inspecting, editing, converting, and analyzing 3D print files, supports 3MF, STL, OBJ, PLY, and GLB.

How to install 3D File Toolkit

This entry records only its repository, not the path inside it, so there is no exact command to give. Open Kikobuf/3d-file-toolkit and copy the folder into ~/.claude/skills/, or the file into ~/.claude/agents/.

What 3D File Toolkit does

Pure-Python toolkit for inspecting, editing, converting, and analyzing 3D print files, supports 3MF, STL, OBJ, PLY, and GLB. Detects source software (Bambu, Orca, Prusa, Cura, Fusion 360, etc.), checks compatibility across 15 CAD and slicer programs, and works with any AI coding agent (Claude, Cursor, ChatGPT, Manus). Zero dependencies beyond numpy
