Medical 3-Layer Stethoscope Keychain for doctor

Create a unique and premium personalized stethoscope name keychain! Designed beautifully with a 3-layer color system. Features a smart dynamic X-scaling algorithm (auto_logo_scale_x) that stretches the stethoscope horizontally to fit longer names automatically while maintaining exact vertical proportions and safety margins. Equipped with a global scale slider (global_scale) to scale the entire keychain up and down proportionally with ease, and advanced zero-gap direct letter connections (the stethoscope cleanly terminates exactly at the letter boundaries with no gaps and does not cross above the letters). Choose from 3 base backing styles: "Contoured" (perfect silhouette flush backing), "Rectangle" (chamfered box backing), or "None" (elegant wireframe print). Supports batch printing up to 10 keychains with unique names arranged in a beautifully centered grid layout. Fully customized with playful, highly printable Google Fonts (Pacifico, Fredoka One, Chewy, Baloo 2, Comfortaa, Lobster, Lilita One, Permanent Marker) compatible with MakerWorld's Customizer!
