What is Gridfinity?

Where it comes from

Gridfinity was designed by Zack Freedman and published in 2022 as an open standard. Anyone can make and share compatible parts, and there are now thousands of them: bins, tool holders, labels, lids and baseplates. Boxie is an independent planner built on the standard and is not affiliated with its author.

The numbers that matter

• Grid: 42 × 42 mm cells. A box covers whole cells, such as 2 × 3.
• Height: units of 7 mm. A 3-unit box is 21 mm tall, plus the stacking lip on top.
• Clearance: a box is 41.5 mm across, half a millimetre less than its cells, so it drops in easily.
• Base: every cell has a stepped foot that sits in a pocket of the baseplate.
• Stacking lip: the top edge is shaped like a baseplate, so boxes stack on each other.
• Magnets: optional 5 × 2 mm magnets in the corners of the base hold boxes in place.

Bins and baseplates

A Gridfinity setup has two parts. The baseplate lies in the drawer and gives the grid its pockets; the bins stand in the pockets and hold your things. You can use bins without a plate, but the plate stops them sliding and lets you lift one out and put it back in the same spot.

How to start

1. Measure the inside of your drawer.
2. Work out the grid: divide each side by 42 mm and round down.
3. Plan which boxes go where, and how tall each should be.
4. Print the baseplate, then the boxes, a few at a time.

A Gridfinity planner does the maths

Boxie handles steps two and three for you. Enter the drawer's size and it fits the grid and splits the baseplate for your printer; draw the boxes on the grid, shape each one, and download every STL file in one zip.

Printing tips

• PLA or PETG with a 0.4 mm nozzle and 0.2 mm layers works for almost everything.
• Two or three walls and low infill (10–15%) keep bins light and strong.
• Neither baseplates nor bins need supports: print them flat as they come.
• Watch the first layer: the base profile has to come out clean for a box to sit well.
