This is a 3D printable servo horn designed specifically for the Losi Mini-B when using the SX107 servo. It’s a direct-fit replacement that matches the stock geometry, making it perfect for repairs, spares, or custom setups.

The horn is designed for strength and precision, with a snug spline fit to minimize slop and maintain accurate steering response. Ideal for racers and bashers who want a quick, printable solution without waiting on replacement parts.

Features:

  • Designed for Losi Mini-B
  • Compatible with SX107 servo
  • Direct fit – no modification required
  • Strong, compact design suitable for racing or bashing
  • Great as a spare or backup part

⚠️ For best results, ensure your printer is well-calibrated so the spline fits tightly on the servo shaft.
