We are using security keys for authentication at work, and I wanted to make cases for the most important keys we have.
I laser engraved and cut the window for the case out of acrylic, and embedded it into a 3D printed case. Worked surprisingly well on the first try.
The key used here is Yubikey Bio FIDO2 edition: https://www.yubico.com/products/yubikey-bio-series/
Can you guess why I chose to use that specific image?
