Gridfinity storage

Modular bins and baseplates on the 42 mm Gridfinity grid.

Gridfinity is a popular modular storage system: bins sit in a baseplate of 42 mm cells and stack on a 7 mm height grid, so drawers and shelves become reconfigurable. This generator emits a spec-accurate part built from ordinary primitives and booleans — a hollowed bin body over the standard stacked base (optionally with magnet holes, a label tab, and a stacking lip), or a baseplate of matching sockets. The base is the published profile exactly: a 0.8 mm chamfer, 1.8 mm straight, and 2.15 mm chamfer rising to the 41.5 mm foot. Baseplate sockets are 0.25 mm per side larger so bins drop in, and the stacking lip is the matching profile, so a bin nests into the one below instead of perching on it. Wall thickness is adjustable, from the standard’s 0.95 mm minimum up to 2.6 mm — it changes nothing the standard fixes, so the foot, the socket and the lip’s mating faces stay exactly where they are. Screw holes run the full height of the base and open into the bin, which is how a bin is bolted down to its baseplate from the inside. Because it is a node tree, every part re-opens in the property panel and stays parametric. Compartments divide a bin into an equal grid, separated by the standard’s own 1.2 mm divider — the compartments are sized so that wall comes out exactly, and the outer wall keeps the thickness you set. A division too fine to print is left out rather than cut as slots. Lid builds the published base on its own: it is the exact geometry a stacking lip is shaped around, so it nests into any spec bin and drops into any baseplate.

1. Open the Generate panel from the left sidebar and choose Gridfinity (under Storage).
2. The part drops in as editable primitives you can further tweak. The parameters open in the Properties panel, where you set them.
3. Pick Bin or Baseplate, then set the width and depth in grid units (1 unit = 42 mm).
4. For a bin, set the height in 7 mm units, adjust the wall thickness, and toggle magnet holes, a label tab, and a stacking lip.
5. Split it into compartments across and deep, or switch Type to Lid for a cap that nests into a bin’s stacking lip.
