SPECIAL HOZO BRANDED EDITION AVAILABLE with custom insets for NeoBlade and M-Cube:

My Gridfinity case system was built from the ground up following Zack Friedman's official Gridfinity spec.

I designed it primarily for my own needs: consistent 5×4 footprint with mostly 6U height boxes and the option to go 7U for the occasional larger item. I wanted a large, comfortable front handle (I have big hands 😉), dual latches, reinforced hinges, support for a ⌀2mm rubber seal, full stackability with a proper top handle, and a clean overall look — all while using only two screw sizes.

Compared to other popular systems, I simplified where I didn’t need extra size options and improved the ergonomics and design for my workflow.

Like most of my designs, this one started as a personal project. If you like the choices — great! If not, there are plenty of fantastic alternatives out there. No plans for larger sizes — for those I use my awesome Einhell Gridfinity System which allows you to stack two layers of 6U bins in a 9x6 grid.

Free to use and print. Hope it serves you well! 👍

Half-Grid lids available as well via separate print profile:
