I didn't find an existing single-piece gridfinity base to fill out the top compartment of my US General Mini Toolbox (Harbor Freight) to use with the H2D toolkit, so I made one. This was generated with the magnet holes sized for the “HFT Rare Earth Magnets” in claimed 5/16" x 5/64" (roughly 8x2mm) available at my local Harbor Freight. I likely won't fill them but wanted to have the compatibility for future options with magnet-attached gridfinity components.

I printed with Bambu Basic PLA on textured plate.
