Build a Gridfinity drawer insert

A baseplate and two bins, built by a generator instead of by hand.

This is the first project where you do not model anything. Gridfinity is a modular storage standard built on a 42 mm grid, with bins stacking on a 7 mm height grid, and the Gridfinity generator knows all of it: the foot profile, the socket clearances, the stacking lip. You choose how many cells and how tall, and it produces an editable node tree.

That is the point of a generator, and the reason to reach for one here. The numbers a published standard fixes are not yours to get wrong — get the foot profile out by a fraction and your bin will not seat in anyone else's baseplate, including your own next print.

Sizing it to a real drawer is the only measuring you do: divide the drawer's width and depth by 42 and round down. Four by three units is 168 × 126 mm, which is worth checking against your printer before you commit — if it does not fit, drop a unit and print two smaller plates, because they tile on the grid anyway.

One wrinkle worth knowing: the tile inserts a bin at its defaults and puts the numbers in the Properties panel, so you size it after it exists rather than before. Switch Type to Baseplate there and the height field greys out, along with everything else that only a bin has.

Open Help → Build a Gridfinity drawer insert in the editor to build it hands-on, step by step.

1. Open the Generate panel and choose Gridfinity; set Type to Baseplate at 4 × 3 units.
2. Open it again, switch Type back to Bin, and make a 1 × 1 bin three height units tall with a label tab.
3. Move the bin clear of the baseplate so both parts print side by side.
4. Generate a second bin, 2 × 1, for a longer tray.
5. Run the print check — the baseplate is the part that may not fit your printer — then export.
