Bitcoin Cold Wallet - Mneumoic Storage

This is a Bitcoin 24 word tumbler storage.

The idea is that you only need the first 4 letters of each word for the words to work. Lots of information online about this.

You will need to print 8 cogs as there are 4 chars per side. Then you print in batches the total letters you need. I did this in big blocks so there was still no way to know what words i was making. The letter chips will snap into the cog. I printed this with a Prusa so my tolerances where very clean. If you have a messy printer you might have to resize to get this all to fit.

I then used the nutstick to push a nut into the hole and use a M3*20 bolt with nut to secure the two ends together.

Enjoy!
