Gridfinity Builder

Start with the plates that fit your printer and your drawer, then fill them with boxes sized to what you're storing. New to printing for the shop?

Baseplates

Gridfinity Plate Generator
Grid pitch is fixed at the real Gridfinity 42mm -- changing it would make the result incompatible with actual bins and accessories, which defeats the point.

Pick a drawer below and this works out how many whole 42mm units fit it.

~23.5" x 16.5" interior. The bottom drawers on some ALEX units are deeper; this is the standard drawer size.

14 x 9 units (588.0 x 378.0mm grid footprint).

That needs 6 printable plates (3 x 2) at this bed size.

Your drawer has 9.0mm left over on the right and 41.0mm left over on the bottom -- a whole 42mm unit won't fit there, so the plates along that edge are widened by that amount instead of needing a separate piece -- marked +filler in the print plan.

The defaults below are right for almost everyone -- only change them if you have a specific reason to.

With neither of these on, the sockets are cut straight through: an open grid you can see the drawer bottom through, using a fraction of the filament. That's how most printed baseplates are made.

Only added where two plates in this layout actually meet -- a drawer that only needs a single plate gets none, whether or not this is checked.

Print plan

What you'll actually print: each square below is one whole plate (never a fraction of a grid unit), sized to fit your printer bed. Plates marked +filler have a flat, socket-less strip baked onto their right and/or bottom edge to reach the drawer's actual wall -- everyone else is pure grid.

Boxes

Boxes built to the published Gridfinity standard: the stepped foot that seats in a baseplate, a stacking lip, compartments with label tabs and scoops, and pockets for magnets or screws. It tells you what the finished box measures as you go.

Size
Gridfinity is metric and fixed: 42mm across the grid, 7mm per height unit. Everything here is in millimetres.

Sized from the grid: each unit is 41.5mm of box plus the 0.5mm gap between neighbours.

Left alone you get one compartment filling the box, a standard stacking lip, 1.2mm walls and no hardware -- which is the box most people want.

Finished size

83.5mm x 83.5mm x 24.6mm (width x depth x height, lip included)

21.0mm of that is the box; the lip adds 3.6mm, which the box stacked on top sits into.

It occupies 2 x 2 cells of a baseplate, and holds 15.1mm of depth inside.

Useful Gridfinity Models

A handful of community-designed models from MakerWorld that turned out genuinely useful for woodworking tools -- these aren't ours, just ones worth knowing about. Every card links to the original, where the designer gets the credit. See also 3D Printing for Woodworking in Resources for more, beyond just Gridfinity.
