I designed this box for a number of reasons: * Needed to keep some spare rolls of toilet paper near the toilet. * I dislike having random scattered items sitting around the bathroom. * I especially dislike having toilet paper rolls fall off the back of the toilet and roll around on the floor. * I wanted something enclosed to keep everything clean. 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.
