I took the original remixed box, extended the bottom to 3" deep and have included two inserts. The shallow insert is curved to match the interior bottom of the box and the other is deeper and fits on top. Was a tight fit, I've reduced inserts to 99.5% to insure that your print should go inside the box. I'd print the bottom of the box and then the first smaller insert and insure it will go inside. Then print the second and the lid and locks. I used 3mm screws to hold things together at hinges. Same as original. I made to store the many assorted USB cables and some power wall warts I had laying around in a couple of drawers. Print some clips if you want to insure they stay secured when you pull out. Thanks!
