The Spiral Passthrough Fidget is a simple yet highly engaging desk toy designed for smooth, continuous movement. The internal spiral geometry allows the core to pass seamlessly through the outer body, creating an endless sliding loop that is both calming and addictive to use.

This fidget is optimized for easy 3D printing with no supports required and tight but reliable tolerances for a clean passthrough action right off the printer. Its compact size makes it ideal for desks, backpacks, or pockets, while the spiral design adds a visually appealing mechanical aesthetic.

Perfect for stress relief, focus, or just satisfying tactile motion, this fidget is great for both beginners and experienced makers. Print in a single color for a clean look or use multicolor filament to highlight the spiral motion.
