Sun Watch - Sundial wristwatch - any 20mm strap

Bring the oldest timekeeping technology into the 21st century! This Wearable Sundial Watch is a fully functional, 3D-printable wrist sundial that blends ancient astronomy with modern design. No batteries, no screens, no gears—just you, the sun, and thousands of years of history right on your wrist.

Perfect as a conversation starter, a steampunk accessory, or an educational project for kids and tech enthusiasts.

⚙️ How it works:

1. Align the watch with North (you can use your phone's compass).
2. Read the local solar time directly from the dial!

You DON'T need spring bars to attach strap! You just need to cut 25mm of filament! 20mm strap fits into my design :)

Please, give me your feedback!
