"Not your keys, not your coin!"

In order to truly own cryptocurrencies, it is vital to protect your private seed by all means. One popular strategy is to inscribe the seed onto stainless steel washers so it can be safely stored somewhere very very secret.

This tool makes it much easier to line up and stamp washers for a quicker, more legible result!



Made to work with these specific products, results using other sources may vary:

• [3mm Letter Stamps](https://amzn.to/3OqtTHQ)
• [17.45mm(5/16" ID) Stainless Steel Washers](https://amzn.to/3GPUqsr)
• [GreenGate3D Recycled PETG Filament](https://bit.ly/coolGrey)
• [Ninjaflex TPU Filament](http://bit.ly/ninjaFLEX)

Optional: I printed the first 3 layers using [Ninjaflex TPU](http://bit.ly/ninjaFLEX) and then switched to [GG3D PETG](url) (PLA printed solid should also be fine). This adds a grippy surface to the bottom of the print so the tool doesn't slide around.
