Bitcoin and crypto currency tamper-proof paper wallet

thingiverse

These containers make quick work of printing tamper-proof paper wallet crypto currency holders. A simple yet elegant physical wallet, this is a really straightforward design that ensures your private key remains unseen. It's easily breakable open for when you need to use it. Print QR codes for both the wallet address and private key, making sure only the wallet address shows through. Use a translucent filament color so you can see the QR code right through the container - as seen in the photo, QR code readers have no problem reading them through the container. Insert a stopping point or filament color change at around 3mm to insert your QR codes before sealing up the container with your private key inside. Alternatively, print without QR codes and use these containers as conversation starters to help spread the word about crypto currencies. Let me know what other coin or token you'd like to see added to the list and I'll make it happen. Print at .3 with no infill for a fast print time (12 minutes) - my Prusa spans 30mm with no infill just fine. Add a small dab of super glue on the QR code to keep it flush with the bottom of the container, ensuring clear visibility. It also helps prevent the extruder fan from blowing the QR code out while printing. I use QR Monkey to generate QR codes - test them first to make sure they read correctly before using them. Some generators produce funky QR codes that won't scan. https://www.qrcode-monkey.com/#bitcoin
