Gridfinity M2-M5 Stackable Fastener Bins

Do you have a pile of screws and fasteners laying around in random bins and containers, waiting for a project to be attached to?

These Gridfinity bins are my solution to itch my need for organization, while helping sort all major M2, M3, M4, and M5 screw sizes. These are stackable bins at 4 Gridfinity units high each. I included 1U-wide and 2U-wide bins for most sizes. Some of the sizes, such as 40mm or higher need 2U-wide bins only. If there's a bin size you might want that is missing, send me a message and I can create it and add it into the profiles.

There are a number of print profiles for this overall model. For each profile, I've included PETG and PLA versions for everything, including single color and multi-color options (for the embossed labels). Also, within each profile, there are magnet and non-magnet versions that fit standard Gridfinity setups. The profiles are:

M2 Button Head screws
M2 Nuts and Washers
M3 Button Head screws
M3 Head Cap screws
M3 Nuts and Washers
M4 Button Head screws
M4 Nuts and Washers
M5 Button Head screws
M5 Nuts and Washers

UPDATE Jan. 27th 2026: By request, I've added M2 1U and 2U 2x20mm bins for both PETG and PLA profiles. This is available in multi and single colors, magnets and no magnets.

UPDATE Oct. 3rd 2025: By request, I've updated the M3 Nuts and Washers print profiles for both PETG and PLA to add a new 2U bin labeled “M3 Washers”. This is available in multi and single colors, magnets and no magnets.

These are part of a set of Gridfinity organizer bins for screws, heat inserts, and rugged containers. Others in this set are:
