How to make custom Gridfinity bins
- Measure your drawer. Divide its inside width and depth by 42 mm to see how many grid squares fit.
- Print the baseplate. Choose Baseplate, set the size, and print it flat. Several small plates can sit side by side.
- Design the bins. Set each bin's size in grid squares and its height in 7 mm units. Add dividers for small parts.
- Choose the extras. Stacking lip to stack bins, 6 × 2 mm magnet holes for a firm hold, and a label shelf at the back.
- Print without supports. Print bins upright at 0.2 mm layers with 2–3 walls. Every overhang is 45° or less.
Questions
What is Gridfinity?
An open, free modular storage system by Zack Freedman: bins on a 42 mm grid that drop into baseplates and stack, so you can rearrange drawers any time.
Are these bins compatible with other Gridfinity models?
Yes. They follow the standard 42 mm grid, 7 mm height units and the standard foot profile, so they fit Gridfinity baseplates from other makers.
What magnets do Gridfinity bins use?
6 mm × 2 mm round magnets, pressed into the holes under each grid square.
How tall is a Gridfinity bin?
Height is counted in 7 mm units; a 6-unit bin is 42 mm plus the 4.4 mm stacking lip.
