Primary Structure

• The structure consists of an elliptical track, U‑shaped partitions, and precision‑matched ball bearings, all crafted from PLA‑based plastics—commonly used in 3D printing—with a distinct printed layer texture on the surface.

Functional Applications

• This compact, desktop‑friendly stress‑relief toy uses inclined tracks to guide balls along predetermined paths, delivering a relaxing and engaging decompression experience. It also serves as a creative display piece for 3D printing enthusiasts.

Design Features

• The design is straightforward and easy to print, with highly adaptable dimensions for both the track and the ball bearings. By tweaking the track geometry or adding additional partitions, users can expand the gameplay possibilities—such as incorporating multi‑ball interactions or designing intricate, multi‑path layouts.
