What

An oloid is a three-dimensional geometric shape formed by the convex hull of two perpendicular, linked circles, known for its unique rolling motion where every point of its surface touches the plane. The oloid was discovered by Paul Schatz in 1929 and is defined as the convex hull of two congruent circles placed in perpendicular planes, with each circle's center lying on the edge of the other circle. -- Wikipedia

Design

Two interlocking disks are used to form the structure. It rolls similar to the solid version of the oloid. However it won't be exactly the same due to the thickness of the disk.

Printing

• You need to print two of this.

• No support is needed.

• Example print setting: 2 walls + 15% infill but it should print fine with other settings of your choice.

Assembly

• Observe the cutout and notch location.

• Slide in to each other until you hear a click.
