Highly Detailed Anatomical 3D Models

I am compiling a teaching library and need a series of highly detailed, print-ready anatomical 3D models. The collection must cover the full skeletal and muscular systems, major organs, the complete gastrointestinal tract, the central nervous system, and key embryological stages. Accuracy and anatomical fidelity are critical because the models will serve as hands-on study aids in a classroom setting.

Please deliver watertight STL (or OBJ) files that are already oriented for 3-axis FDM and resin printers. Wherever practical, separate complex assemblies into logical, snap-fit or keyed sub-parts so students can disassemble and explore internal structures. Model size should be scalable without loss of definition; surface resolution must support fine features such as foramina, nerve roots, and embryonic morphologies.

Acceptance criteria
• Geometry passes Meshmixer or Netfabb analysis with no non-manifold edges
• Detail level allows print layers ≤0.1 mm without loss of form
• Named parts match standard anatomical terminology for easy cataloging

If you have a sample of previous medical or educational anatomical work, feel free to share a screenshot or low-res render when you respond.
