3D printers. I enjoy tinkering and fine tuning hardware,firmware, and software. There’s somthing lethargic about taking things apart, maintenance, improvements and troubleshooting that I find very cathartic. The final results in the ability to print whatever I want.

Maybe just tinkering in general tbh lol. If somthings broken, I always see if I can figure out why and potentially fix it or/and improve it. No better feeling than bringing life back to something thats considered dead.
