Active prototypes
Easter Tomb
A printed teaching model links a rolling stone and internal bed motion. Real assembly revealed a cord-routing problem now driving the next drum revision.

Inside the project
Tell the story through a moving model.
- Model the motion
- Print the parts
- Thread and assemble
- Test the revised drums
Where it started
This project explores a mechanical teaching model in which the movement carries part of the story, with a rolling stone and an internal moving bed.
What took shape
Printed supports, shafts and cord drums reached a partial physical assembly. Assembly research and a 3D viewer help explain how the parts are intended to work together.
What the work revealed
The cord hole barely met its groove, making threading difficult in the printed part. The correction focused on the two drums, adding clearer access and paired cord holes while preserving the rest of the mechanism.
The next step
Print and thread the replacement drums, then check the complete motion before treating the mechanism as finished.
