I designed this box for a number of reasons:
And so, this box was born.
It is designed specifically for the toilet paper used in my house and may need to be modified to suit your purposes - the OpenSCAD file is provided so you can modify it if you need to. As rendered, the top is a very loose fit - I like it that way, but there is also a tunable parameter for that.
Materials:
The pictures box was printed using eSUN Warm White PLA. It's somewhat translucent, which allows you to check to make sure you have spare rolls in the box without opening it. The rendered STL file for this has walls set to 1.6mm so that it's a multiple of a standard 0.4mm nozzle. If you change or resize this box, due to the thin walls, I'd recommend setting it to a multiple of your nozzle diameter so you can print the walls with just perimeters and no infill. Also, for a top/bottom infill, concentric tends to look pretty nice, but it does take longer - I used it for the top, but used rectilinear for the bottom since it's not often seen.
