This is a robust, 3D-printable lockring tool specifically designed for removing and installing the chainring lockring on Generation 2 e-bike motors. Essential for cassette or chainring maintenance and replacement. The design is based on the official interface of Bosch Gen2 motors.
Key Features:
- Precision Fit: Engineered with the exact 8-tooth geometry to securely engage the lockring.
- Dual-Use Interface:
- Large hexagonal base compatible with a standard wrench or socket.
- Transverse hole for a Tommy bar or a large screwdriver to apply higher torque.
- Functional Design: The hexagonal form factor and solid construction make it durable.
Recommended Print Settings for Durability:
- Material: MUST be printed with a strong, impact-resistant filament. PLA is too brittle.
- Recommended: PETG (best balance), ABS, Nylon (Nylon-CF for extreme durability), or Polycarbonate.
Usage Note: Remember that this is a plastic tool. While it is strong, you should apply torque carefully. If a lockring is extremely stuck, a metal tool may be required to prevent stripping the plastic teeth. Ensure the lockring threads are clean and lubricated before re-assembly.
