What is Gridfinity?

The idea

Gridfinity is an open storage system designed by Zack Freedman. You print a baseplate that fits your drawer, then print bins in any size that click into the grid. Bins can be moved, swapped and stacked, and everything stays put.

Because it is an open standard, bins from this site work with baseplates and bins from other Gridfinity designs.

Sizes

• The grid is 42 × 42 mm. A bin of 2 × 3 units has a footprint of about 84 × 126 mm.
• Height is counted in units of 7 mm. A 6-unit bin is about 42 mm tall, plus the stacking lip.
• Bins are made 0.5 mm smaller than the grid so they drop in easily.

Where to start

• Measure the inside of your drawer and divide by 42 to see how many units fit.
• Print a baseplate. If your print bed is too small for the full drawer, print several smaller baseplates and lay them side by side.
• Print a few general bins, then add special ones: bit holders, battery bins, tool bins.
• Use the filler tool for the leftover space around the baseplate so it doesn't slide.

Magnets and screws

Bins and baseplates can have holes for 6 × 2 mm round magnets, which keep bins in place when you pull a drawer open. Screw holes are for fixing a baseplate or bin to a surface. Both are optional: bins sit well without them.

Printing tips

• PLA is fine for almost all Gridfinity parts.
• No supports needed: the feet and stacking lip are designed to print without them.
• 0.2 mm layers and 2 walls are plenty for bins. Baseplates benefit from a little more infill if they carry heavy tools.
