It is just a box and lid, nothing special. I made this to use as a container for a tile game I am working on creating. The box lid has rounded corners so that it isn't applying any pressure to the box.

I designed this in Autodesk Inventor. I use Slic3r and I used 15% infill for the box and the lid and 175 micron resolution. I would suggest using 350 micron resolution to speed up the printing time, (at least for the box).

This is easily scaled if you want to make multiple boxes. I scaled it to 1000% for what I wanted.

Printed with Gold and Green Hatchbox PLA on my Monoprice Mini V2. Since I am using a $200 printer, there are some bumps on the edges which can easily be removed via sandpaper.
