Would it be possible to use a 3D printer to create some sort of object to be used for bitcoin?

I was thinking that it could have a public key/QR code on the outside and a private key on the inside.

BTC could be sent to the public key to fund the object, then, to collect the bitcoins, you would have to destroy the object in order to access the private code.

Any thoughts?

Thanks. For extra security you could even integrate a tamper-evident hologram for extra security.

There may be a use for 3D printers here. Physical bitcoin may be something you want to conceal or disguise until you are ready to use them.

Any significantly advanced cryptocurrency is indistinguishable from Ponzi Tulips.

Good concept but a few kinks need to be worked out. plus it would probably be more susceptible to theft.

I wouldn't say there are too many kinks to work out,
I made a physical object which holds some btc.
Make a paper wallet folded up. During construction,
I put the piece of paper carefully inside the part.
part finishes completely, and now the object holds the coins.

This concept can definitly apply to a ridiculously large range of parts/products.
Only you would know that the little plastic cat on your window is actually a stash.

It would be pretty awesome to have a seamless box which contains a private key inside. No lid, no hinge, no screw holes. Just a cube. Have to use a hacksaw just to get the goodies within.

It'd be neat, but a 3D-printed one would be too easy to counterfeit.  One reason Casascius coins are so trustworthy from a security standpoint is how complex and detailed (microscopically!) the holograms are, as well as the fact that no reputable hologram printer will print the same one for someone else, since it is stored in some international database.

Just like nobody would ever dare to counterfeit fiat money like EUR or USD, right? No reputable printer would ever dare to do that...

Well, they wouldn't be reputable for long after that!

Yea it might not be that easy to trust someone elses 'homemade coins', but purely for personal savings, it's a nice way to hold an offline wallet
