There’s a filament saving variant where you can use toilet rolls or other waste cardboard for the walls:

3d printing is great, but a lot of wasted plastic if you print large organizers and stuff like that.
I think maybe I've been on fark too long. https://m.fark.com/comments/6611712/Woman-discovers-boyfrien...
You don't have to be Adrian Monk to recognize that toilets are unsanitary.
And fwiw, I don't really care either wherever people use them for whatever they want, I am just still confused why people would want to use paper (sourced from leftover toilet utensils), which is notorious for being basically un-cleanable... as food storage, but to each their own.
I'm surprised how many people hate me for such (imo) mellow statement though
But I don’t think most people are using gridfinity as food storage.
But the article/video we're commenting on doesn't do so, so that's fair I guess?
I don't really think anyone other than OCD/germaphobes thinks about toilet paper rolls in that way and it's certainly not "notorious". I'm pretty sure the general sentiment is that it's a perfectly benign material, often given to kids to play and craft with.
The same thing happened with that episode of mythbusters about the toilet ploom from flushing. A bunch of OCD/germaphobes lost their minds and have not stopped thinking about it since. Meanwhile the rest of society gave a collective shrug and couldn't even be bothered to move their toothbrush brush to another room or close the toilet lid while flushing.
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.
It's just a black hole that I choose not to get into by not printing stuff that's expected to be in contact with food.

If this is a problem, you should buy a new printer that actually keeps the filament conduits away from the hotend. This is a health hazard regardless of food safety - decomposed PTFE is nasty stuff to breathe in.

Fair enough, but I would also say that you should be purging old filament anyways before starting a new one. My slicer does this by default.
> Or in fact any of the various coatings of the heated bed or leftover trace amounts of previous prints...
These days, heated beds are covered in PEI. That's food-safe too.
I think your take is a little panicky and not supported by the evidence. It is perfectly fine to print single-use food stuff out of PLA, especially if you just have a roll or two of the pure (undyed) stuff around. You're much more likely to get sick from the food itself than the plastic it touched for a little while, and PLA is relatively biodegradable compared to most other plastic foodware.
The filament is still in contact with the PTFE tube, the PTFE tube is also hand-cut by me and in motion with the head so it undergoes wear. Even when you get an all-metal hotend there are ways of contamination by PTFE passing through the hot-end and degrading into harmful chemicals.

I do purge and cold-pull. While this removes the bulk of the old filament it does not remove all trace amounts of it.

It is food-safe only if it was produced in a food-safe manner and was kept food safe afterwards, including no contact with pollutants.
Since you mention evidence, I have no way of proving that anything I produce is food-safe. Literally not anything in my extrusion path is certified food-safe, let alone I have equipment to test.
The fact of the matter is that glass, ceramic, and stainless steel has replaced any vessels that are in contact with food at home, and I don't intend to look back on that, and I am in fact looking to replace anything in regular contact with human skin with non-synthetic/non-plastic alternatives -- this includes clothes, bed sheets and others.
While there is the hacking mindset, people also need to be responsible, and my red lines on that is making stuff with a safety aspect to it. Food safety is safety as much as fire and electrical safety in my book.
There are food safe coatings though, these deal with the problem by making your 3D print not in contact with food.
Even so, if you want to be perfectly safe then apply a coat of polyurethane varnish and let it fully cure. That will seal any holes or voids where bacteria might grow, insulated from cleaning solutions.

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.
In my household with 3 adults, we go through maybe a roll every 2 weeks or so. It's almost exclusively used for number 2 business though, so maybe that accounts for some of that difference.
Or, we just use very different types of paper, and yours require more of it for the same effect. :)
You may suggest whatever you want :) We do have an installed bidet in our main bathroom, as most houses where I live has those. Tried it, didn't like it, will proceed with using paper as currently it doesn't have many drawbacks and doesn't leave me feeling "more dirty" afterwards than using water would.
Another improvement may be to make the top and bottom pieces stackable along with the snapping grid system compatibility.
