Description

This is the complete digital package for the Tiny Marble Clock.

Included:

• All 3D print files (STL)
• The original FreeCAD design file
• The full source code
• No documentation or notes

Important

This is not a kit.
This is not a step-by-step build guide.
And this is definitely not beginner-friendly.

The files are exactly as used in the project.
That means:

• The FreeCAD file is not cleanly structured
• The code is functional, but not beautifully organized
• Some design decisions are iterative and experimental

This package is intended for people who:

• Enjoy digging through real-world engineering projects
• Want to study how the mechanism works
• Like reverse engineering and improving things
• Or simply want to support the channel

If you are looking for a polished product or guided experience, this is not it.

If you want the raw mechanics behind a €21 3-axis pick-and-place marble clock, you’re in the right place.
