Customizable 3DS Cart Holder

This is a customizable cartridge holder designed to hold Nintendo DS / 3DS cartridges. I made it because just about every 3DS cartridge holder is either the usual "carry case" style (where you slot them into a thing that holds 6 carts on each side), or they're part of a piece that also displays the console next to the games, or they're just designed to hold a handful of games.

I've got about 100 loose Nintendo DS / 3DS games and they're just sitting in a bag, so I made something I could put them in, vertically, and sit in a drawer with my other cartridges.

This is flexible enough to be used for other stuff too. If you tweak the parameters, you can make a holder for PS5 games, or you can make a box to hold screws for projects, or a pen holder, whatever you want really, as long as it's in a grid formation.

It also has the option to make a lid that just sits over the top. It doesn't lock in place or anything like that, it's just a piece that is slightly larger than the holder and
