Socket Extension Storage - Gridfinity

I wanted to make a socket extension storage for my gridfinity system.  This is a 7x3 box so you will need a 300x300 build bed or will have to split the model.  Holds 3/8" and ¼" socket extensions of standard lengths.  My tools are Kobalt and were modeled to those parameters.  Other brands likely have similar measurements but I cannot guarantee.
