DND Stats tracker

I made this tracker to allow someone who doesn't like to use apps or constantly erase on paper to track things like their gold and character's health. You simply insert a BB in the 1's 10's 100's . . . place to represent any number. Most of the sections are three digits, but the gold section is six digits. I also made one that allows you to put a custom title in a slot so that you can easily track anything you want to. Feel free to make your own tags to go in that section or if you leave a comment, I can make a tag for you to 3d print and insert in the title section. The other trackers I made that do not have custom title capabilities are made to track:
weight, gold, rations, HP, ammo, and spells.
I ended up changing the tracker from arrows to ammo in the final design in order to make it less specific and therefor more versatile.
I also left room for you to store the BBs in the case and a magnet to remove the BBs from the spot you put them in.
