3dprint

Use when the user wants to present or inspect STL models in the browser (a single self-contained HTML viewer page, works offline) and/or physically simulate a ball rolling through printed geometry (marble runs, tracks, funnels, tunnels) with the trajectory animated inside the viewer. Complements design-stl (static PNG previews + printability checks) with interactive 3D and dynamic validation.

Use when the user wants to slice an STL and print it on a Bambu Lab printer over the local network (LAN), preview an STL in 3D in the browser, or check/monitor a Bambu print's status. Covers slicing with Bambu Studio or OrcaSlicer, uploading over LAN, starting a print behind a confirmation gate, and streaming progress.

Use when setting up the Bambu LAN printing workflow for the first time on a machine, or when print-to-bambu preflight is not all green — installs/locates the slicer, sets up the Python venv, scaffolds bambu.toml, helps find the printer IP/serial/access code, and walks through enabling Developer/LAN Mode so prints can start.

Use when the user wants to create or design a 3D-printable STL model from a description (e.g. a molecule, a part, a parametric shape) rather than starting from an existing STL. Generates geometry with Python/trimesh (default) or OpenSCAD, renders previews, validates printability, and iterates. Pairs with print-to-bambu to actually print it.
