Bin configuration
Gridfinity grid sizing, magnet holes, and print options.
Gridfinity basics
Gridfinity is a modular storage system where bins snap into a baseplate grid. Each grid unit is 42mm × 42mm. Tracefinity generates bins that conform to the Gridfinity spec.
Bin editor layout
The bin editor has three panels:
- Left — configuration sliders and toggles.
- Centre — 2D top-down canvas where you place and arrange tools.
- Right — live 3D preview of the generated bin. Updates automatically as you change settings or move tools.
Configuration options
| Setting | Range | Default | Notes |
|---|---|---|---|
| Grid width | 1–10 u | 2 | Each unit is 42mm |
| Grid depth | 1–10 u | 2 | |
| Height | 1–20 u | 4 | Each unit is 7mm + 5mm base |
| Cutout depth | 5mm – max | 20mm | Max depends on height |
| Clearance | 0–5mm | 1.0mm | Gap around tool outlines |
| Magnet diameter | 3–10mm | 6mm | Standard Gridfinity magnets are 6×2mm |
| Magnet depth | 1–5mm | 2.4mm | Slightly deeper than magnet for press-fit |
Toggles
- Magnet holes — adds magnet recesses in the bin base. On by default.
- Corners only — magnet holes only in the four corners instead of all grid positions.
- Stacking lip — adds the Gridfinity stacking lip so bins sit flush when stacked. On by default. Adds ~4.4mm to total height.
Placing tools
Drag tools from the sidebar onto the 2D canvas. Tools snap to position and you can rotate/flip them to fit the layout.
Bed splitting
If the bin dimensions exceed your printer's bed size, Tracefinity automatically splits it into printable pieces and exports them as a ZIP. You can set your bed size in the settings. The full merged STL is also offered for large-format printers.
