I created a parametric box script in OpenSCAD to make some custom storage boxes. My 11 year-old son asked if I could make him a box to hold a deck of Pokemon cards. He requested it have a Poke Ball on the front of the box and on the lid. I am anticipating he will be asking for more of these.

I included the OpenSCAD script. It is parametric and has the ability to create a box and lid in any size with dividers (in both X and Y). It can also round the corners as desired. The Poke Ball decorations can be easily removed and/or replaced with anything you desire. Enjoy!

Print and clean up. I had to shave down the box/lid mesh zone a little to make the box easier to open and close. The boxes I made with rounded corners (radius = 5mm) fit well without any shaving.
