This is a version of @classy_274492's Gridfinity Toolbox (Parametric) which can be found here:

I wanted a Gridfinity Toolbox in the 6x2 form factor, so I could use 2x1x6 windowed bins with all their windows clearly visible. My printer wasn't large enough, so I cut up the parts up for printing on a smaller bed. The maximum dimensions required are now 168x84x29mm so you can print this on almost anything.
The hinges are separate pieces so they can be printed on their sides to improve strength. They then slot into the longer base or lid parts (this was inspired by AleksanderSpyr_86950's comment on the original design). See my screenshot for the recommended print orientation.
The longer parts are joined with a bowtie for good alignment. To each baseplate or lid is added a 250mm M3 steel rod through the whole length of the part to improve its strength. All parts of the lid or baseplate are then permanently bonded with CA glue.
Other parts (clasp hinge and clasp arm) are reused from the original design, and you will still need all the additional hardware as per the original design.
The result is not pretty (espicially if you get CA glue everywhere, and print with the wrong settings, like I did!) but is strong and functional.
You can make the toolbox as many layers tall as you want, just buy more hardware and print more parts. You will need per layer:
and per toolbox:
If you are adding them, you can use CA glue to secure up to 48 x 6x2mm magnets per layer in the provided slots (optional, but cool!).
Mind the orientation of the lid hinges when assembling everything - the hinge inserts are not quite symetrical, the thinner edge should be at the top and the wider edge at the bottom (see the picture).
You may need to use an extra-long 3mm drill to clear out the hole for the 250mm rod if your printer is not well dialed in. Or you might get away with hammering the rods in, if it's close.
