DIY Washer Jig Kit – 3D-Printed Crypto Seed Backup Tool With 14 Metal Washers, Screws & Nuts

About This Product

If you take crypto security seriously, this DIY washer jig is a smart way to create a fireproof, waterproof backup of your seed phrase.

It's a 3D-printed tool that holds M8/24mm washers and 3mm stamps securely so you can stamp your seed words into metal – no paper backups that can burn or get wet.
It's a rugged, long-lasting solution for protecting your Bitcoin or blockchain wallets.

The kit includes 14 metal washers, plus a pair of screws and nuts – basically everything you need to get started.

Just supply your own metal stamps (3mm) and a hammer, and you're ready to go.

The design holds the washers firmly in place while you stamp, so you get clean, legible imprints every time.
It works whether you have a 3D printer or just buy the pre-assembled tool.

It's perfect for anyone who wants to take custody of their own keys without relying on expensive commercial products.

The tool itself is lightweight and compact, and the washers stack neatly for storage.

Note: instructions aren't included, but the design is pretty intuitive for anyone familiar with basic DIY tools.

Great for Bitcoin enthusiasts or as a gift for crypto-savvy friends.

Peace of mind in a small package.
