Bin configuration
Gridfinity is a modular storage system where bins snap into a baseplate grid. Each grid unit is 42mm x 42mm. Tracefinity generates bins that conform to the Gridfinity spec.
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 + 4.75mm base |
| Cutout depth | 5mm-max | 20mm | Max depends on height and stacking lip |
| Clearance | 0-5mm | 1.0mm | Gap around tool outlines |
| Cutout chamfer | 0-3mm | 0mm | Bevel on top edge of pockets |
| Magnet diameter | 3-10mm | 6mm | Standard Gridfinity magnets are 6x2mm |
| Magnet depth | 1-5mm | 2.4mm | Slightly deeper than magnet for press-fit |
| Insert height | 0.5-10mm | 1.0mm | Only shown when insert is enabled |
| Insert fit | 0-1mm | 0.2mm | Clearance shaved off insert edges so it drops into the pocket |
| Bed size | 150-500mm | 256mm | For auto-splitting oversized bins |
Toggles
Magnet holes -- recesses in the bin base for magnets. On by default.
Corners only -- magnet holes only at the four outer corners instead of all grid positions.
Stacking lip -- raised rim so bins stack securely. On by default. Adds approximately 4.4mm to total height and reduces maximum cutout depth.
Raise lip -- extends the wall and stacking lip upward by this many units (7mm each) above the floor face, leaving the interior open. Use it for shallow bins where a tool protrudes above the floor: the raised lip lets a stacked bin clear the protruding tool. 0 = standard (lip sits at the floor face). Shown only when the stacking lip is on.
Contrast insert -- generates a separate STL to print in a different colour. The pocket is deepened automatically to accommodate the insert thickness.
Partial Bins -- disables individual grid cells, removing them from the shell.
Connect Base -- disabled cells keep the base plate connected instead of being fully removed.
Retain outer wall -- keeps the outer bin wall around the full perimeter when connect base is on.
Auto grid sizing
On by default. When enabled, grid width and depth automatically adjust to fit all placed tools, and the grid width/depth sliders are disabled. Toggle it off to set grid size manually; the sliders become active again.
Default bin settings
Defaults can be saved at two levels:
- Global -- stored in browser localStorage. Apply to all new bins. Set from the bin editor or settings page.
- Per-project -- stored on the project via the API. Override global defaults for bins created within that project.
Use "Save as defaults" to capture the current bin config. Use "Reset defaults" to restore factory settings (2x2 grid, 4u height, magnets on, stacking lip on).
Partial bins
The partial bins option allows you to disable individual parts of the Gridfinity box to save filament. By using a matrix that matches the grid width * grid depth, specific parts of the box can be enabled or disabled.
Bed splitting
If the bin dimensions exceed your configured bed size or the bin model is separated by the partial bins configuration, Tracefinity automatically splits it into printable pieces. You get:
- Individual STLs for each piece (also available as a ZIP).
- The full merged STL for large-format printers.
- A split preview in the 3D viewer.
