SBox meets Gridfinity - stackable toolbox system compatible with Gridfinity

Zack Freedman's Gridfinity system still doesn't have a robust portable toolbox option as far as I know. So I decided to mix the robust, interesting design of Michal Fanta's SBox Mini with that of the Gridfinity system.

This remix is an upscaled version (111%) of the SBox Mini parts, to accommodate a 4x4 baseplate for the Gridfinity system. At this scale, the ‘small’ bottom bin of the SBox Mini can accommodate a standard Gridfinity container + one at half height.

I've merged the baseplate to the model, but my modelling skills are rough. So the implementation isn't ‘by the book’, but it's functional and should print just fine without any visual blemishes. At this scale, all parts still print on a typical Ender baseplate (220x220).

The required hardware (metal pins - see the original SBox Mini model) will have to be upscaled accordingly; I've used 3mm steel rods cut down to size for the pins, and they work well, with a little play depending on the how well your printer is tuned. Any pins that might feel like sliding out you could ‘lock’ into place with superglue, or a small dab of hot glue for a less permanent fix (= my recommendation).

Remark: a few of the holes on the bottom bin that are used to fix the latches on the side are undersized. This seems to be an issue in the original SBox Mini model. I will update the file once the creator of the original has corrected this. For now you could widen those holes with a 3mm drill.
