Anatomically Correct Magnetic Human Heart 4-Color

Unlock the mysteries of human anatomy with this stunning, high-definition 4-color model of the human heart. Designed for educators, medical students, or anyone fascinated by biology, this model isn't just a static display piece—it is an interactive learning tool. The heart is meticulously split into two sections, held together by six strategically placed 6x2mm magnets. This allows you to "crack" the heart open to reveal the intricate internal structures, including the chambers, valves, and chordae tendineae, all rendered in life-like detail. If you wish to use printed connectors instead they are also provided in the file.

Every vessel, from the superior vena cava to the descending aorta, has been carefully colored to reflect anatomical standards, making it as accurate as it is beautiful. Whether you are looking for a unique desk accessory, a classroom aid, or a challenging project to test your multi-material printing capabilities, this model delivers.

Printing Instructions

To ensure the best results and functional magnetic fit, please follow these guidelines:

• Print Orientation: I highly recommend printing both halves in the upright orientation provided in the 3MF file. This preserves the internal detail and ensures the magnet holes remain perfectly circular.
• Material: PLA (Matte Red, Blue, and White/Cream work best for a realistic look).
• Layer Height: 0.16mm or 0.20mm (0.16mm is preferred for the finer internal valve details).
• Infill: 15% Gyroid (for structural strength).
• Supports: Required. Use "Tree Supports" (Auto) for easy removal, especially around the internal chambers. Use a heat gun when removing the supports, as some parts (especially veins/arteries) are VERY delicate.
• Hardware Required: 6x Magnets (Size: 6mm Diameter x 2mm Thickness).
• Assembly Tip: A drop of superglue (CA glue) in each magnet hole will ensure they stay seated permanently. Double-check your magnetic polarity before gluing!
