I snapped the elevator arm from my crack yak XL (which is already a printed part originally). This is a compatible replacement that will snap onto any 5mm rod.
The fit might depend on your printer tuning. Just scale the model a few % up or down in your slicer as needed, for the perfect fit.
For a “right hand” orientation, simply mirror the part in your slicer.
The author marked this model as their own original creation.
