v1.1
April 2, 2025

Improvements

  • Pivot bolt changed from M6x20 to M5x20 for a slimmer, easier-to-source fastener
  • Lower Dogbone grip slightly loosened to simplify assembly while maintaining secure clamping
If you are updating an older build, adjust your BOM and spares to use an M5x20 pivot bolt. Mixing M6/M5 hardware between versions can cause fit issues.

New Ring Design

Added v1.1 57AIM Ring with improved mounting features. This is now the recommended default ring for 57AIM motors and supports the Gold Motor covers.

Organization Updates

  • Refactored file structure for clearer organization
