It consists of three interlocking, planetary-style gears that mesh together. When you rotate one gear with your thumb, it drives the other two in unison, creating a continuous, satisfying tactile loop.

How It Works

• The Mechanism: It uses a synchronized gear train where the teeth fit perfectly together, transferring motion across all three wheels smoothly [LAm7LzNYqsE].
• The Purpose: It serves as a pocket-sized sensory tool to help with focus, anxiety relief, or ADHD, giving you a smooth, mechanical resistance to fiddle with.
• The Design: It is optimized for 3D printing, meaning it is designed to print completely flat on your build plate. Depending on the version you have, it either prints fully assembled as one single working piece (print-in-place) or as a few snap-together parts.

Here are the optimized 3D print settings and model details to ensure smooth, functional gear operation right off the print bed.

Recommended Print Settings

• Layer Height: 0.2 mm (provides a great balance of print speed and smooth gear teeth).
• Infill Density: 15% – 20% (ideal for durability without wasting filament).
• Infill Pattern: Gyroid or Grid (adds excellent structural strength for constant spinning).
• Wall Loops: 3 (strengthens the gear teeth to prevent snapping over time).
• Top/Bottom Layers: 4 layers (ensures a solid, flat surface finish).

Post-Processing Tips

• No Support Needed: This model is designed to print completely flat on the build plate without messy supports.
• Bed Adhesion: Use a brim only if you experience warping on the outer gear edges.
• Break-In Period: If the gears feel slightly stiff immediately after printing, spin them back and forth for 30 seconds to smooth out any micro-imperfections.
