You know how there is this debate of whether or not toilet paper should face us? It may say that it should in the patent, but that doesn't stop people from taking the toilet paper in my house off of the roll, flipping it around, and putting it back on. Now, we can't stop people from believing that it shouldn't face us, but we can stop the hassle of having to change it back when they flip it over. This is the purpose of this device. It is easy to put on a new roll of toilet paper, it swivels so that instead of taking off the toilet paper and flipping it over, your friends can just turn the holder. It is printable in one piece, and will function properly once you take off all of the supports. However, you will probably need to make weak supports so that when you twist the area that swivels to break the supports, you won't break the device as a whole.
The object is 6.12 inches tall, 4.37 inches long, and 7 inches wide. The model is small so that the stl file used will be under 1 megabyte, and because not every roll of toilet paper is the same size, you will need to change the size of the object so that it can hold the rolls of toilet paper from the brand you desire. The printing time will vary depending on the size of the object and the model of your printer, and the infill is your choice. I recommend weak supports (or none, if your printer can manage it) so that you are able to print the object in one piece.
