STIHL FS50C Starter Repair Part

Replacement repair part for the recoil starter mechanism compatible with STIHL FS50C and similar trimmers.

This part was designed as a replacement for the original worn or broken starter component.
It is intended for repair and DIY restoration purposes.

The model was tested with FDM printing and optimized for strong layer adhesion and mechanical durability.

Recommended Print Settings

• Material: PETG minimum

  • Nylon or other stronger engineering materials are also recommended for maximum durability
