The quick change toilet paper holder works like any other TP holder, it holds toilet paper. The difference with other holders shows when you need to replace the roll of paper. The design makes changing a roll of toilet paper a breeze. While it will not safe hours a day, it will make changing a roll of paper just that bit easier.
I will not claim full credit, this design has been around for a while, it is based on Japanese ingenuity. I simply rediscovered it and decided that it would make a good 3D print. It is apparently a Toto, I have included a gif.
The holder has two pivoted fingers that can move up. When a new roll of paper is pushed from underneath, the fingers move, releasing the old roll. Then when the new roll is high enough, the fingers fall down again, locking the new roll in place. This system hardly adds to the complexity of the design but adds a ton of functionality.
Building it is fairly simple. It consists of five 3D printed pieces, some glue, 2 M4 bolts and a 4mm axel. First attach the fingers to the body pieces. Put them in place and put the screw in the back of the frame. The fingers are have holes that are slightly off center. Make sure to put the finger with the thickest part toward the TP side, so that the fingers fall under their own weight. Next put the axel through the lid. The last step is to glue the two halves of the holder together with the lid in between. Once the glue has set, the holder is done. You can now attach the toilet paper holder to a wall of your liking.

Thank you for the very cool holder! I downloaded the files and printed everything… only to discover that the holder is too narrow for the Costco generic TP that we use. Is there any way for you to possibly widen the whole thing a little? It looks like the width of the opening of the two parts after assembly is slightly more than 4.25 inches. The TP we use is exactly 4.5 inches wide… so I would need an opening slightly wider than that so the roll could still turn.
If you are unable to make the changes… would you consider letting me have the CAD files so I could modify them myself? I’m a complete novice when it comes to CAD, but I have some friends who could probably help me with it. If not… I completely understand, but figured it was worth asking. 🙂
Oh, and the ZIP file had 2 additional file that I printed… not realizing that it appears to be a second version of the design. You might want to add a note there to let people know they are two different designs.
Thanks again, and really love your site… so many fascinating things here. Especially the powder printer…!
I have done it slightly different for now. You will see an additional download button which contains spacers. 1cm, 3cm and 8cm. In your case the 1cm should be enough, but if you want to make a kitchen roll holder, it should also be possible (Probably 1x 1cm, 1x 3cm and 1x 8cm).
Let me know how it works out, if it doesn’t, I will make an extra design slightly bigger, but I think the spacers are a more versatile solution for everyone.
