Modular Watch (The Plastipan)

The Plastipan is a 3D-Printed recycled modular watch created for easy personalization and built with sustainability at its core. It combines a Miyota 8205 automatic movement with a layered construction: laser-cut acrylic disks act as both crystal and backplate, paper dials slip under the hands for instant graphic changes. Everything that can be 3D printed is: case and strap, no expensive tools required.

This is still a beta, any feedback is appreciated. Improvements to the design are welcome.

The Plastipan’s parts can be printed using recycled and biodegradable filaments, allowing makers to minimize environmental impact. The Plastipan name comes from Plastic + Mazapán. After prototyping, I noticed the small, domed shape of the watch resembled one of my favorite Mexican candies, the mazapán.

I'm currently working on a build video which I will upload on Youtube.
