I made this a while ago. It’s a simple cheap clock mechanism with five layers of laser cut clockage. Inspired by the amazing work of Eric Freitas.
I designed the cogs in Corel Draw and then cut and engraved them on Gale’s Zing 30watt laser. Then I spray painted each part. The cogs don’t move, but it does (or did) tell the time. The number 3 and VII are laser cut paper.
