I made a tiny Nintendo Switch Christmas ornament

I made the body of the Switch in Fusion 360 and had it SLA printed online (was $1 for the body, $1 for 25 thumbsticks, and about $16 for fast shipping), then hand-painted it. PCB was designed in KiCad and I ordered it along with a solder stencil so I could reflow solder it on a hotplate.
Since the ESP32 has wifi (credentials configured via a json file on the SD card), it syncs time using NTP so it can automatically play different gifs on Christmas day! I also set it up so firmware updates can be done either by dropping a firmware.bin file on the SD card, or using ArduinoOTA over wifi (in the video you'll see me using a programming jig, but that got tedious after a while, so the OTA is much nicer whenever I don't need to look at the serial log).
Let me know if you have any questions!
