An old colleague of mine went through the process of doing gridfinity. One of his main struggles was getting boxes that fit his power tools perfectly. He was looking for a way to easily get a shape of the tool into CAD. What’s the most straightforward and effective way to get a CAD representation of a solid these days? Of course there are expensive solutions but is there anything reasonably achievable in the DIY spac…

I don’t recall the specifics at the moment but YouTuber Uncle Jessy showed how to take a custom box in his gridfinity video.

While theoretically you can get certified food-safe blend of PLA, the rest of the extrusion path must also be food-safe... I personally am not fond of eating hot degraded PTFE...

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.

> purging old filament anyways before starting a new one. My slicer does this by default.

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

> These days, heated beds are covered in PEI. That's food-safe too.

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.

YMMV but when my work area changed from "big pile of junk" to "semi-organized", it removed a lot of the friction I had for just starting projects. I need a tape measure? I know exactly where one is, it has a dedicated 3D printed holder on my pegboard which lets me get to work instead of spending 15 minutes digging through drawers and shelves.

Yes? My tape measures are in the tape measure box. White metal cabinet, lowest shelf on the right, cardboard box marked "tape measures." There's a dozen or so tape measures in there. Same place they've been the last 30 years. Making a custom enclosure for every tool seems over optimized and wasteful. If I were to attempt this, it would take decades and I'd never see a return on productivity within my lifetime.

I’m not sure if having a box in a drawer in the cabinet with 10 tape measures is the flex you think it is

You go through a roll in a couple days?

I'm not sure if you're trying to say that's a lot or little? But yeah, each roll might survive 3-4 days at most I'd guess, but honestly can't say I've ever measured. We're two people (me and my wife) in the household fwiw.

Feels like a lot. Even 3-4 days does. I'm not judging though!

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. :)

Took me a while before i understood it was to store physical items. For a second I was thinking some battery solution-like grid storage system. A few photos on the homepage would help a lot and make it much more clear for noobs like me.

Based on the title alone I was thinking it was a solution for storing grids... not that I had any idea what kind of grid one might need to store.

Resisted this for a long while, instead using a series of plastic organizers in various sizes, eventually settling on the Storehouse 10 Tray Organizer Utility Box from Harbor Freight which organizer size matches that used for selling a fair range of hardware on Amazon --- then, when I dropped one, breaking the dividers/separators in the box and went to look for a replacement discovered it was out of stock locally and…

This. Every commercial system I've used changes or is discontinued. I now take my storage into my own hands, even if it takes longer.

I standardized on Sortimo t-boxx for our workshops:

... and although the insert colors changed, the architecture and sizing has been constant for more than 15 years ...

Usually you don't use your toothbrush while fondling your genitals...

There are way more bacteria in your mouth than on your genitals

I feel like invoking the zeroth law of thermodynamics here.

I am not personally turned off by the hygiene of toilet paper rolls, but I think any rational adult's Overton Window should accommodate those who are. Your condescension is grossly unwarranted. You don't have to be Adrian Monk to recognize that toilets are unsanitary.

Eh, it got a chuckle and eye roll outta me so I didn't mind. 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

> notorious for being basically un-cleanable

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.
