agent-3d-workbench
Local 3D workbench where people and agents edit, model, verify, and prepare prints without a CAD license.
What it does and how it connects
Agent 3D Workbench is a local 3D workbench where a person and a general-purpose AI agent share one project, model and selection. It imports GLB and STL files, lets the agent model with Python, CadQuery or Blender code, split and repair meshes, build cavities, lids, head shells, locating pins and joints from explicit dimensions, and prepare prints with orientation, plate arrangement and STL or 3MF export. Local code needs no 3D service key; the user can also connect their own Hunyuan or Assembly service.
Editing is shared and inspectable: select a part, ask the agent to edit it, inspect the change and undo it. The README walks through a worked example in which a 63 mm tall Pikachu STL became a 13-part head-shell draft with magnetic closure, all parts passing watertightness and sampled assembly checks, while noting the result was not printed or test-fitted and forward vision stayed blocked.
It is a plugin developer preview at 0.9.0; the standalone Agent application is not included. It is tested on macOS, with Linux and Windows pending. It needs Git, uv, Python 3.12 or later, Codex desktop and a Codex CLI with plugin support, plus Blender, Node.js or slicing software when a task needs them. Agent subscriptions and any 3D service fees are the user's own.
