The Dark Spin - Batarang Fidget Spinner

Model Overview & Print Notes

Unleash your inner vigilante while keeping your hands busy! 🦇 Designed from the ground up as a sleek, ergonomic desk toy, this Batarang Fidget Spinner features an integrated print-in-place ball bearing mechanism right at its core. No metal bearings, screws, or extra hardware are required—just slice, print, and spin straight off the build plate!   ⚙️ Recommended Print Profile (Printing Settings): Layer Height: 0.16 mm (Optimal for super smooth rolling spheres) or 0.20 mm (Standard) Wall Loops / Perimeters: 2-3 walls for extra strength on the wing tips Infill: 15% - 20% (Gyroid or Grid recommended; increase to 50% if you want heavier spin momentum) Supports: None (100% support-free design) Brim / Skirt: No Brim (Avoid brims so the internal bearing balls remain free to roll) Elephant Foot Compensation: 0.15 mm - 0.20 mm (Crucial to prevent the first layer of the bearing balls from fusing to the ring) Recommended Filament: Matte Black PLA (as pictured), PLA+, or PETG.
