Bin configuration

Gridfinity grid sizing, magnet holes, and print options.

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

Grid width1-10 u2Each unit is 42mm

Plan limits: Free accounts can create up to 2 bins. Pro accounts can create up to 20. See Plans and Limits for details.

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.

Contrast insert -- generates a separate STL to print in a different colour. The pocket is deepened automatically to accommodate the insert thickness.

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 are saved to your account. You can set them at two levels:

  • Global -- apply to all new bins. Set from the bin editor or settings page.
  • Per-project -- 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).

Bed splitting

If the bin dimensions exceed your configured bed size, 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.
