底座環螺栓左

Took a while to find the exact replacement for the left side, but this genuine bolt clicked right in and the device feels sturdy again — no more wobbling during use. Glad I could fix it instead of buying a whole new setup.

The left-side bolt fit my device perfectly and locked in place with no wobble, so the whole setup feels solid again. It's clearly the real spare part, not some flimsy knockoff, and that peace of mind is worth every penny.
