  1. A total of 4 different features were measured on a 3D printed model using physical (calipers) and digital photographic measurement strategies. The features were additionally measured from the source model STL file using Autodesk 3D Studio Max. A total of 7 different geometries (model wall thickness and model opening diameters) were measured
