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.
- Cutout chamfer — bevels the top edges of tool pockets for easier tool insertion.
- Insert — generates a separate STL to print in a contrasting colour. The pocket is deepened automatically to accommodate it.
Auto grid sizing
When enabled (on by default), the grid width and depth automatically adjust to fit all placed tools. Toggle it off to set grid size manually.
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.
