This is my own design that I'm copying over from Thingiverse here. (Created account here because I've been finding Thingiverse buggy).

I modified this parametric design from thingiverse https://www.thingiverse.com/thing:4757317

My modified version is sized for MiniDiscs with their sleeves.
I have also made this parametric, so with Fusion 360, you can put in the number of minidiscs you want to store (must be an even number) and the model will re-build.

I couldn't figure out how to place an SVG in a relative location, so it's placed manually.
If you want the logo, and change the size of the box, you'll need to open the sketch, highlight the logo, and move it.

The pictured 20 MiniDisc box I made was a gift for someone so I also cut their name and 'MiniDiscs' into the lid, and glued it in.

I only used 2 perimeters and PLA plastic which is not very flexible.
The lid catch snapped off, so I glued it back on, with a thin piece of steel inside.
Now it's really strong.

I've generated STLs for 10, 16, and 20 discs.
