Bitcoin and crypto currency tamper evident paper wallet by misbach

These are quick and easy to print crypto currency tamper evident paper wallet containers.
This is a really simple and elegant physical wallet. It's tamper-proof so you can be assured the private key has not be seen. It is easily broken open for when you want to use it.
Print QR codes for both the wallet address and private key. Ensure only the wallet address is showing.
Use a translucent filament color so you can see the QR code through the container (see photo). The QR code readers have no problem reading the QR code through the container.
Put a stopping point or filament color change in your print at around 3mm so you can insert the QR codes before the container is sealed up with your QR code inside.
Or, you can print without qr codes and use them as conversation starters to help spread the word about crypto currencies.
Let me know what other coin or token you'd like to see and I'll add it to the list.
Print at .3 with no infill so it goes fast (12 minutes). My prusa spans the 30mm distance with no infill just fine.
Put a small dab of super glue on the QR code to keep it flush with the bottom of the coin so that it shows through clearly. It also helps the extruder fan from blowing the QR code out while printing :-)
I use QR Monkey to create the QR Codes. Make sure you test reading the QR codes before you use them. Some QR generators are funky and I couldn't read the QR codes they produced.https://www.qrcode-monkey.com/#bitcoin
