Features

• Layout Planner — Drag-and-drop bin placement with stacked layers and color-coded categories
• 3D Preview — Isometric visualization of your drawer layout
• Bin Designer — Parametric 3D bin generator with STL export
• Baseplate Generator — 3D-printable Gridfinity baseplates with automatic splitting and STL / STEP / 3MF export
• Print List — Optimized print list with filament, time, and cost estimates
• Inspiration Gallery — Browse curated example layouts across workshop, kitchen, office, hobby, and personal themes
• Cloud Sharing — Share layouts via link with optional real-time collaboration
• Cloud Sync — Sign in with Google or GitHub to sync your layouts and bin designs across devices
• PWA — Installable, works offline

Scope

To set expectations, this tool deliberately does not:

• Slice models for printing — export STL / STEP / 3MF and slice in Bambu Studio, PrusaSlicer, OrcaSlicer, etc.
• Replace general-purpose CAD — the Bin Designer is parametric but stays within the Gridfinity spec; for arbitrary shapes use Fusion, OpenSCAD, etc.
• Require accounts — layouts live in your browser by default; signing in for Cloud Sync and link-based sharing are both opt-in
• Support legacy browsers — needs a modern browser with WebGL support

Built With

• brepjs — Parametric 3D geometry & STL export (OpenCascade WASM)
• Three.js — 3D visualization
