This is a motorized tool designed to help you create stunning, perfectly symmetrical designs with ease. The machine rotates your egg smoothly, giving you full control over your patterns and allowing for precise, beautiful results every time.

The setup is powered by a gear-reduced DC motor and can be controlled in two ways:
✅ Recommended: using a compact PWM motor controller with a knob (e.g. ZHITING 1203BB) — it’s cheaper, simple to use, and works very well.
⚙️ Alternatively, you can still use an ESC with a servo tester setup if preferred.

Power is usually supplied via a 3S LiPo battery, but a regular 9V battery block can also work for low-speed operation or testing.

Needed Parts:

🔌 Electronics:

• 1× 12V DC Gear Motor – 550 RPM, Ø37 mm shaft (e.g. Greatisan Geared Motor)
• 1× PWM Motor Controller – e.g. ZHITING 1203BB (preferred)
  • Alternatively: 1× Brushed ESC + 1× Servo Tester
• 1× Battery – 3S LiPo recommended, or standard 9V block (for light use)

🔩 Hardware:

• M2 Heat-Set Inserts – RX-M2x4, brass (e.g. ruthex or similar)
• M2 Mounting Screws – various lengths

   Bearings:

• 1× Ball Bearing – 21 mm outer Ø / 15 mm inner Ø / 4 mm depth
• 1× Ball Bearing – 22 mm outer Ø / 8 mm inner Ø / 7 mm depth

  🛈 Note: When using the ZHITING PWM speed controller, make sure to download the additional STL file named
  “Egg Spinner Control Box (Smaller For PWM DC Motor Controller)”, which is specifically designed to fit this controller.
  Alternatively, you can also select the other printing profile that's made for this smaller box — both options will work.
