How to use the instruments

1. Use ONE Instrument
Use either your Left (cyan) or Right (amber) hand to pass the needle. Keep your other hand visible in camera view.
2. Grab the Needle
Move one open tip ring into the top circle until it turns green, then pinch.
3. Rings 1 → 2 → 3 → Release
Pass left Ring 1, rotate through center Ring 2, exit right Ring 3, and open inside the top-right Release Ring.

Reduced graphics — fewer shadows and a lower pixel density.One hand — keep one hand in view. The other instrument hides.Easy pickup — keeps the tips at the needle depth and snaps it into the jaws. Turning this off enables free 3D depth and resets the needle.

Only one hand needs to hold and pass the needle (Left cyan or Right amber). Keep your unused hand comfortably visible in the camera frame so tracking stays active.
