8" Lenart Sphere Set w/ Straightedge & Two-Piece Torus Stand Many Available

This listing is for an 8-inch clear acrylic Lénárt Sphere set, ideal for spherical geometry instruction, STEM demonstrations, optics experiments, and creative projects. Included are three components: the 8" transparent sphere, the spherical straightedge used for drawing or measuring great-circle arcs, and the two-piece split torus stand that supports the sphere securely. The torus stand measures approximately 3.75" inner diameter and 6.25" outer diameter, designed to cradle the sphere while allowing rotation and study of spherical surfaces. The straightedge measures roughly 8.59" in arc length and fits the curvature of the sphere for accurate marking. This set works well for educational use, mathematics exploration, display builds, art installations, or as replacement parts for a Lénárt Sphere kit. Multiple sets are available; buyers may contact me for bulk pricing or combined orders.
