The top 4 views are screenshots of the 3D CAD solid model
"shaded with edges", the next 4 are screenshots
from some 2D views with just the lines and the last 4 are
Keyshot renderings.
This 3D CAD model is available in my webshop at www.dbbpshop.com,
when you buy it you can choose from SEP, IGS, X_T or OBJ formats,
or just download all of them!
