Tired of having to hunt for that roll of soft tissue every time you do your business? If only there were a fashionable hook upon which you could place this precious velvet!
Fortunately for you, oh bachelor or bachelorette, Science has heard your cries and has an answer! What you are seeking is called a toilet paper roll holder, and they are none too difficult to acquire! Sensible people would go to the store and buy a nice wooden or metal one to match their decor, but who are we kidding? You're either desperate or have no sense of taste, so join the club and print yourself one now!
This design is inspired by Charles Pax's filament spool holder. You'll need a Thingomatic with a slightly taller than average (116mm+) build height in order to construct it.

Tips for printing: Use a large nozzle and larger layer heights to save time.
No infill necessary (unless you want to)
There are in-built holes at the back of the model, designed for small nails (pictured) so you can attach it to the wall. The nail head should be no longer than 4mm in diameter.
My printer failed towards the end because I had a snag in the filament (no fault of the model or the printer!), so in the photograph of the one I've printed, the ends facing you are open - the model is actually designed to have rounded-off, closed edges. If you manage to print one all the way to completion please upload I would love to see it! :-)
Thanks for looking!
