I had a toilet paper holder "Grundtal" from IKEA for a long time now. It broke just a few hours ago, so I got inspired by it and made a model to print a substitute. That should not break so easily
I printed it with 2 perimeters and 20% infill. But I would recommend to print it sturdier.
After nearly 10 months of usage without any breaks or cracks I guess the settings are perfectly fine.
Designed in FreeCad feel free to remix ;)
