Backup TP Holder

Free to download on from July 5 to July 11, 2024

Another design made at my wife’s request… she saw something like this at a friend’s house and asked me to make it. It is a hook onto the tank spare toilet paper holder so you always have a backup ready. Especially good for any washroom used by guests since they may not know where to find the spare TP. This one works super well and I believe will work on any tank.

Not a whole lot more needs to be said, it just rests on the lip of the tank and you drop on a roll of paper. I designed this based on the very large Costco Kirkland branded rolls so I am pretty sure it will fit and other sizes out there.


I have tried to make my main print settings visible on the Cura screenshot but in case they are difficult to read I have summarized them again here…


Material: Because it is exposed to water I recommend using PETG but I think any material will work fine.

My Setup:
Nozzle = 0.4mm

My Settings:
Layer height = 0.2mm
Line width = 0.4mm
Wall count = 4 (1.6mm)
Infill = 40%
Ironing = Not important.

Designed to print without support.

Print Orientation: As shown in the screenshot(s).

Assembly Notes

No assembly or post-print processing is required.

Use, Licensing, Comments and Feedback

My primary distribution site for my design files is is, in my opinion, leading the way in promoting designers and competition amongst designers which in turn fuels the growth of high-quality 3d printable designs for the benefit of our entire community.

Also, please like and save to help me with the competitions.

I do not permit the use of my designs for commercial purposes (i.e. you can not sell my design(s) or products printed from my design(s)) without first acquiring a commercial license from me. On I offer membership accounts for access to all my design files as well as a membership for commercial licensing which allows subscribers to sell printed products using my designs.
