Project Expired patents - "Reviving Forgotten Inventions"
I search Google Patents for intriguing expired patents and bring them back to life—because I believe they’re either interesting, funny, or genuinely useful. Once I find a design that inspires me, I recreate it as a 3D model and print it using a 3D printer.
My goal is to give life to old ideas and show how creativity from the past can still have a place in our modern world.
