3D Printed Wallet for Seed Words

This wallet is made for BTC and can hold up to 12 or 24 words, based on the BIP39 standard. You can find the binary equivalents for the words on GitHub. It's super handy for places like airports because, being 3D-printed, it won't set off metal detectors. It's wallet-sized too, just like a credit card. You can punch holes in it with a nail or any solid tool a hammer works if it’s heavy enough.

Totally agree, it’s compact and great for security in travel situations. Makes it way easier to stash away your BTC!

But like, how do you even write a seed word with holes in it? Seems kinda impractical...

Right? But still, it’s a cool idea for securing your BTC, especially in crowded areas like airports.

Sure, not a replacement for a real wallet, which should ideally be metal-engraved. But these are convenient for travel, multisig wallets, or even a lightning wallet. If you mess up the holes, just print a new one.

So you just use a nail? I heard the card version is based on the 1248 pattern, while the square one follows binary. You can find instructions on the GitHub Bitcoin repo for the BIP39 words that you’ll engrave.

Have you actually used one? Is it reliable? Where’d you get yours?

Yeah I’m curious too! I’ve never seen a wallet like this, especially 3D-printed.

The cool thing about the 12-word version? Keychain hole for orientation. But the 24-word one? Confusing because it has holes on both ends can be tough if you flip it over.

I wonder why you'd want a wallet with the words on it... How does that even work? Haven’t been keeping up with physical wallets.

It’s not too hard to figure out orientation. Just check the left side. If it starts with two circles instead of four, you’re good. The concave part of the circles is the front.

This feels a bit off-topic for a general discussion... maybe it should be in the tech section?

You can totally move it yourself as the OP. Just click on that option below your post and you should see a move thread button. If it’s confusing, reporting it for a move works too.

Thanks for the tip! I’m kinda new here and didn’t realize how to do that. Hopefully, I can figure it out.

Hey they’re free to download! If you don’t have a 3D printer, ask a buddy or find someone who does it nearby. Don’t let anyone charge you too much for printing. Works just fine and it’s a fun extra idea. I gave away a bunch of these at the last Bitcoin event!

I prefer the 12-word version over the binary model though I noticed a small error in the sample you provided. The BIP39 word for 512 is actually ‘divide.’ Also, what kind of filament should I use if I’m not too worried about airport checks?
