Rolling Compound of Eight Octahedra (Oloid Variation)

The Rolling Compound of Eight Octahedra is an angular shape inspired by the oloid, rolling in a straight path while wobbling in an S-shaped motion. Built with precise 90° angles, it creates an optical illusion from certain angles, almost appearing like a perfect square or cube. This adds an extra layer of intrigue, making the shape look both structured and organic, with a form reminiscent of a seashell.

Its solid surface feels satisfying to touch, and on a hard surface, it produces a gentle tapping sound as it rolls. The mix of curves and angles plays with light, creating a striking effect whether it’s moving or still.

I've only printed this in FDM using the following settings:

Infill: Gyroid, 20% (Tweak to Preference)

Supports: Not needed if printing in halves. For a single-piece print, supports are necessary and will require some cleanup.

Seam Position: Aligned

Assembly: For best results, print in two halves and glue together.

Feel free to reach out if you have any questions or need assistance.
