  • What is your threat model? If it’s loosing money on your account, then Scrubbles already has posted an answer on security. I’d like to add that many modern credit/debit cards allow you to disable and reenable payment methods as you need it, you can use that to prevent your account getting drained.

    But to me this isn’t the entire answer, as it does little to protect your privacy in case of a data breach. I’ll break down additional things you can do, roughly from least to most effort:

    • Don’t reuse usernames unless you need to build a brand. If one account ever leaks personal information, it’s harder to associate it with the other stuff you do online.
    • Have at least 2 regular emails, one for services that need your personal info, and one for everything else. If needed you can compartmentalize more. Use temporary emails for signups wherever possible.
    • Often you don’t need to fill in real information into forms, make things up and put them as a note in you PW manager in case you need it later.
    • Protect you phone number at all costs. It’s a pain in the a** to change, and companies know it. Always assume you are being tracked if asked for your number. If it leaks, it becomes much easier to build a profile on you.
    • Shipping companies will often ask you for your number. How often have you been called because there were issues? If the answer is zero, they don’t need your real number either.
    • When using 2FA, use Aegis or a similar app. SMS 2FA is vulnerable to a few attacks and again leaks your number.
    • Get stuff shipped to a post box, if available to you locally. There are re-shipping services like a physical VPN if you need an extra layer.
    • Do not use paypal for payment if you want to hide your post address. They automatically give it to the merchant without telling you. Not sure who else follows the same practice, but personally I would not trust google/apple/samsung pay either.
    • If you need best payment privacy, buy a gift card with cash. Should you ever get crypto and want to get rid of it, buying a gift card with it is a good method.

  • The primary concern with fdm printed parts is bacteria growth in the gaps and cracks, which you cant really avoid. Some materials allow vapor smoothing, but the most popular candidates ABS and ASA are not food save, even if perfectly smooth.

    For storing stuff that does not support bacteria growth (for sure salt, maybe tea bags and pepper) PETG is a good choice. Strong consistent layer adhesion enables water tight print. Its relatively chemically robust and will not chemically react with your food, and not leach out much if at all. It also means its mostly dishwasher safe, especially at low temperatures. You MUST have a properly tuned PETG profile to get a close to perfect surface with minimal defects. Burn of any stringing, otherwise it will end up as microplastic in your food.

    For storing stuff that can spoil, the requirements are a lot higher, and the only option is coating with a food safe resin. You should research what is compatible with the printed plastic, and maybe avoid dishwasher or aggressive cleaners.

    It’s worth it for the dry storage and automatic loading alone. Printing multiple objects one after another on the same bed and same print job, but with different materials is also a great feature and huge time saver for small parts. For actual multi-material prints the best use cases are imo writing into the first layer with a different color or using 2 different non-adhering materials for a thin layer between supports and the part. All of these things require very little filament changes and significantly improve the usage experience.


  • That’s because it is cruel.

    Large numbers always seem terrifying, because our human minds are not made for them. The only way to comprehend them is to compare them to other things - in this case all the ways we humans cause damage to the environment directly. Our suburbs are ecological dead zones already. There is just not much space left between asphalt roads, driveways, and neatly trimmed lawn. It’s definitely the cat that goes outside for one hour a day who is the problem. Right next to plastic straws.

    The real frustrating thing about all this that the companies that exploit our planet to core keep doing their shit (Noooo you cant work from home for your office job, you MUST commute to the city daily, because reasons!) while we fight with our neighbors about things that don’t really matter in the grand scheme of things.
