Free-diver Lungs

thingiverse

These 3D medical models illustrate a free-diver's lung capacity, showcasing an impressive 11.9L when using a forced air technique. Both models were created from the same individual, accurately displaying proportions. The lungs are positioned closely together at the front and separated by the spine in back. Print each half separately, glue them together, and use ABS/acetone mixture for an attractive finish after a 7-hour printing time for the packed model.
