I'd be very interested in reading about the kinds of hardware projects you're doing with esp32s and your printer!
Something I've been doing is making an automated hydroponic tent. Temp, humidity, EC sensors and a few servos to control nutrients all feed into an esp32 + servo controller and broadcast data through a local webapp. Just need to add a camera for timelapses and remote viewing.
I have a (very much!) enhanced version of https://github.com/anthropics/claude-desktop-buddy running on a different ESP32 board with a case: https://github.com/nlothian/claude-desktop-buddy-FNK010B/tre...
I have a bunch of Home Assistant controls using a variety of custom controls and cases.
I have a custom version of Seeed's ESPClaw (https://github.com/Seeed-Projects/espclaw - there are a lot of other ESP Claws too) with a case.
I'm working on a Tamgotchi-style mini-game device using ESP-NOW to connect with nearby devices.
Lots of other random projects at various stages of development.
