PDF

This is a unique and fun spinning fidget toy, perfect for spinning between your fingers. Designed for smooth, easy rotation, it's ideal for stress relief, improving focus, or simply as a stylish pocket toy.

The design features:

A static inner ring (yellow) and a rotating outer ring (blue) connected by finger-friendly handles (white).

These outer hooks allow you to easily flick and spin the fidget with your fingers.

The overall shape is optimized for smooth rotation and comfortable handling.

Printing Information:

Material: PLA recommended (PETG or flexible filaments also possible)

No supports needed

Suggested tolerance: 0.2 mm clearance between moving parts for optimal spin

Print orientation:
Print the model flat to maximize strength and get the smoothest bearing surfaces.

Assembly:

No screws, bearings, or glue needed.

After printing, gently break free any tight spots and optionally apply a little silicone spray for ultra-smooth spinning.

Tips for best results:

Print in two or more colors for a beautiful effect!

Light sanding or polishing on contact surfaces can improve rotation.

If you want even faster spinning, use a bit of dry lubricant (like PTFE spray).
