ESP32-S3 USB Authentication Key
A DIY FIDO2 key using an ESP32-S3, a top-to-top type-C coupler, and the Pico-Fido firmware.
This was kind of my introduction to 3D modeling, as I had gotten access to a (frustrating and poorly-maintained) 3D printer when I started my (at time of writing) current job several months prior.
I'd also been wanting a USB authentication key for use with my computers, but didn't want to shell out the cash for a Yubikey. I realized for the same price, I could make my own and have parts left over.
It works well, honestly I've no complaints with the firmware, and am happy with how the casing I printed turned out. I did wind up having to dremel some of the aligment walls for the button and shave it down.
