Thanks for your concern but all my personal data is perfectly safe. I keep it in an old fashioned thing called a "backup" --- complete with encryption.

I maintain 3 copies --- no hosting required. One copy is strapped to my wrist at all times so it is always just as safe as I am --- if not safer.

The linked page say, "3 pieces to be solvent welded together."

Can you say more? What solvent would I use? What material would I choose to make the parts from? (I would be using a service to print the .stl file.)

That’s pretty cool! Especially with how dense microSD cards are these days, you could probably store every (important) photo an average person has without issue, along with the normal documents and whatnot.
