Teepee: Modular Bathroom Crisis Prevention System

It doesn't take any time or money, but I'm a high-schooler who would greatly appreciate winning the free printer :)   –––––––––––––– Picture this: you're home by yourself, sitting on your porcelain throne, and you are ready to depart from your bathroom when you instinctively reach to the side. You reach for it again, but to your dismay, nothing is there, and you slowly look over. Could it be? Could you really have ran out of toilet paper? Now what??? Teepee ensures that this will never happen again. with a modular stacking system, the only limit to how many rolls you can store is your ceiling height. You can use teepee in two configurations, with a receptacle at the bottom that will hold the roll, or with a dispenser and rods for each roll that allows you to use it as a regular toilet paper holder which can “eject” the roll automatically when it is empty, allowing the next full one to automatically roll into the dispenser.   This system should work with 99% of toilet paper rolls, however I have included the f3d file just in case, so the size can be increased. You could also just scale the model up, which should work just as well.     Printing & Assembly:   Printing requires a very small amount of supports for the bottom of each straight piece, as well as supports for the curved portion if you choose to not split it.   As for assembly, any strong glue should suffice, or as an alternative you could spot weld the pieces together. To attach the entire thing to your wall, I would recommend either tape or some sort of adhesive, to prevent making a hole in your wall.   I have also included a test print, as this entire project is filament intensive, it is a good idea to make sure that each piece will fit together properly before printing the whole thing.   Notes:   The dispenser with the ejection system is still quite hairy, and depends on the toilet paper roll. I am working on a more consistent version, but for now I would suggest printing both the receptacle and the dispe
