I bought a 50 pack of bearings on Amazon, and needed a larger gridfinity bin to store them. 2x3x3u high. Obviously does not stack in this configuration, but I've included STEP & F3D files if you'd like to modify it.
I used the Fusion 360 Gridfinity addin here: https://github.com/Le0Michine/FusionGridfinityGenerator
1/10/24 – Uploaded another version with magnet & screw holes.
