If you are worried about this you might want to consider whether you have a healthy degree of concern about hygiene and bacteria. It could be worth speaking with a therapist.

IIUC this is also true of most 3D-print materials. You should not be using Gridfinity to store food! This is also why you usually shouldn't 3D print a dildo.

This would be true even if the materials were food safe to be honest, I don't see how you can keep something like this clean.

It's for storing stuff like capacitors and screws and electrical tape.

You mean like a phone, that you later stick up to your face? I’m sure someone will chime in with how they “never use their phone in the bathroom”, which no one will believe.

> Why do people want to reuse toilet paper rolls?

Because some of us have like 200 cables, and toilet paper rolls is a cheap but effective way of getting some control over these :) And besides, I'm sure that my fingers and feet are more dirty when I touch/move any of the cables, than the toilet paper rolls that spent a couple of days in a bathroom.

Reduce reuse recycle. They are looking for a step two- hopefully they already have bidet, but paper is still useful for drying after.

Maybe paper towel rolls then?
