Clavicle

This is a 1:1 scale scapula.

Identifiable features:
Sternal end
Acromial end
Groove for subclavius muscle
Conoid tubercle
Trapezoid line
Impression for costoclavicular ligament

The model is from the Body Parts 3D Database at http://lifesciencedb.jp/bp3d/?lng=en, which is a NIH funded comprehensive database of 3D anatomical structure data. According to their white paper (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2686534/), the models were constructed from 2 mm interval MRI images of a male volunteer.

I fixed up some non-printable surfaces using Meshmixer, rotated it to the best orientation for a good balance of quality and strength. Large features and landmarks on the bone are easily identifiable, but smaller details may not be visible. These models can be printed on 8" x 8" x 8" or 200mm x 200mm x 200mm 3D printers.
