OrbSpin — Dual‑Orb Spinner (48min, SnapFit, noAMS)

OrbSpin — Dual‑Orb Spinner with Free‑Rolling Spheres OrbSpin is a dual‑orb spinner with free‑rolling spheres and a centered spin core. The orbs rotate without an axle; one is smooth, the other is grooved. The core uses a snap‑fit pin and rotates on a single axis.  All parts are designed for fast printing and reliable press‑fit/snap‑fit assembly.  Available in Large and Small size.   Assembly Core Press the Snap‑Fit Pin into the lower Center Rotation Pin (alignment required).  Insert the Center Rotation Pin through the center opening of the Rotation Body.  Clip the upper Center Rotation Pin onto the lower part while the Center Rotation Pin is inside the housing (alignment required). Orbs Press the Square Insert into one Half‑Orb.  Press the second Half‑Orb on top.  Repeat for both orbs.  Insert each orb from the front/back into its holder; side insertion is not feasible.   Mechanics Orbs: free‑rolling, no axle Core: centered rotation on a single axis Surfaces: smooth + grooved for tactile differentiation     Happy printing!
