3D Printer Simulation

Build a realistic FDM 3D printer simulator using Three.js. Include a detailed printer frame with corner pillars, heated bed with grid, gantry system, print head with heat block and nozzle, a filament spool that spins and shrinks during printing, and a dynamic Bowden tube that follows the nozzle. Implement layer-by-layer printing where each layer is defined by polygon cross-sections extruded at the correct height. Include 4 selectable models (table, fox, vase, chess rook) with different cross-section profiles. Add full orbit controls with mouse drag, right-click pan, scroll zoom, and touch support. Use a clean industrial aesthetic with a light gray background, blue filament accent, and monospace HUD showing layer count, height, and progress.
