Planetary Screw Gear | Fidget Spinners

Planetary Screw Gear | Fidget Spinners 🔩 demonstrates the motion of screw (helical) gears in a planetary mechanism. Designed as a clear and functional model for visualizing gear motion and mechanical principles. Assembly is straightforward — all parts screw or snap together.

• Diameter 82 mm, height 24 mm
• Simple assembly – parts screw or snap together

Assembly guide:

1. Attach 03_Planet Gear to 05_Pivot and 04_Carrier.
2. Insert 02_Sun_Gear and screw it in from below using 06_Screw.
3. Check for smooth rotation.
4. Place 01_Ring_Gear – ❗❗ensure all teeth are engaged! Otherwise you will increase friction and it will not spin properly❗❗
