CarHeart

This modular stethoscope holder is designed to attach securely to the passenger‑side headrest rod of a vehicle. The bell of the chestpiece slides into the dedicated slot for quick access and stable retention. The tubing can either be pressed into an additional channel or simply draped over the heart‑shaped section, depending on user preference. For optimal performance, the heart component should be printed in TPU 95A to provide the flexibility and durability needed for easy interaction with the bell. The headrest‑mounting component should be printed in PETG to ensure strength and heat resistance within the vehicle environment.
