## What Binforge Can Do

1. **Tilted inserts**: Angle any cutout insert from -90° to +90°. Hold screwdrivers at an angle, tilt pliers for easier grab.
2. **Multiple inserts per bin**: Place multiple shape cutouts on a single bin and arrange them freely on a 2D canvas. Mix rectangles, circles, stars, hexagons, photo-traced tools, all in one bin.
3. **13+ insert shape primitives**: Rectangle, circle, ellipse, slot, ring, triangle, hexagon, octagon, star, cross, D-shape, L-shape, T-shape, and text. Plus photo-traced outlines.
4. **Custom-shaped bins**: Select or deselect individual grid cells to create L-shaped, U-shaped, donut, or any arbitrary bin footprint.
5. **Off-grid bin extensions**: Extend bins beyond the Gridfinity grid on any side (left, right, front, back). Useful for bins that overhang a drawer edge or need extra clearance.
6. **Custom baseplate shapes**: Draw D-shaped, L-shaped, or any polygon baseplate outline using the shape editor. Fit baseplates into non-rectangular spaces like curved desk corners or machine enclosures.
7. **Divider skip segments**: Control individual divider segments. Skip specific segments to create pass-through channels for long items like cables or rods.
8. **Visual drawer layout planner**: Enter real drawer dimensions, drag bins onto the grid, see gaps and clearances, auto-generate bins that fill remaining space, export each bin individually.
9. **AI tool cutout from photo**: Photograph a tool on A4/Letter paper, AI traces the outline. Fine-tune with manual polygon editing. Combine with tilt, multiple inserts, and all 80+ parameters.
10. **Auto-split baseplates**: Enter your printer bed size. Oversized baseplates split into printable pieces automatically.
11. **Shareable links**: Share any bin by copying the link. Your recipient sees the exact same design, ready to tweak or export.

## Frequently Asked Questions

**What is Binforge?**
Binforge is a free, browser-based parametric editor for Gridfinity storage systems. It supports 6 part types (bins, baseplates, trays, adapters, layout planner, tool cutouts), 80+ parameters, and runs entirely in the browser with no install and no signup.

**Can Binforge create custom-shaped Gridfinity bins?**
Yes. Binforge supports L-shaped, U-shaped, donut, and arbitrary cell-layout bins. You can also extend bins beyond the grid on any side for overhanging designs. Open the editor at https://binforge.app/app and try it free.

**Can Binforge create custom-shaped baseplates?**
Yes. Use the built-in shape editor to draw D-shaped, L-shaped, or any polygon baseplate. Useful for non-rectangular spaces like curved desk corners. Free, no install required.

**Can I put multiple tool cutouts in one Gridfinity bin?**
Yes. Binforge lets you place multiple shape instances on a single bin using a 2D arrange canvas. Each instance can be a different shape (rectangle, circle, hexagon, photo trace, etc.), independently positioned, rotated, and tilted.

**Can I tilt inserts in a Gridfinity bin?**
Yes. Binforge supports tilting any insert from -90° to +90°. This lets you hold tools at an angle for easier access: screwdrivers, pliers, hex keys.

**Does Binforge work without installing anything?**
Yes. Binforge runs entirely in the browser using WebAssembly. No download, no plugin, no account. Open https://binforge.app/app and start designing immediately. Works on Chrome, Firefox, Safari, and Edge.

**Is Binforge really free?**
Yes. Every feature, every export format, every part type. Completely free. No trial period, no credit card, no feature gates. If paid plans are ever added, existing features stay free.

**What file formats does Binforge export?**
STL and 3MF with multi-object support (separate lid, insert, base). All exports are manifold-certified watertight and slicer-ready for PrusaSlicer, Bambu Studio, OrcaSlicer, Cura, and any other slicer.
