Matthew Chalker recently proposed to his photographer girlfriend in a clever way: he spent 60 hours constructing a customized mechanical iris aperture for the engagement ring.
She said “yes” of course!
Chalker used this Instructables plan as the basis for his box, but he tweaked it to fit his needs. Check out how it came together in the gallery after the break…
Chalker notes on Reddit that he’d love to make another one, but there’s a lot of time and material investment involved in the process. “To complete a full box we’d be looking at $2000-$3000 dollars,” he says. “If you’re interested, send me your contact information and we can talk details!”
