We all love the cheap tools pushers, and our favorite one has a 20-bin portable parts storage case that's just perfect for Gridfinity. I figured out the most efficient layout that I could, and put it together for your printing ease! Based on the Gridfinity Extended models, this includes two plates at 84mm x 110mm to go in the ‘wings’ by the handle, and a 216mm x 210mm plate and 216mm x 191mm plate for the main body. You can arrange them as I have to split SAE and Metric, or push the empty slot to one side. This uses standard Gridfinity bins that are 6 units tall - or if you sand the inside of the clear cover flat, it will fit 7 unit bins nearly perfectly.
