[coccoliths] morphometrics for 3D printing

[Fabrice MINOLETTI]

Dear all, 

I'm working with (geo)student of the FabLab here in Paris. 
Their objective is to construct 3D models of coccoliths for teaching purpose. 
These models are made with OpenSCad and use simple volumes (squares, cylinders, polygons) and simple operations (rotation, translation, ecc). 
The downside of this approach is that we need quantified morphological parameters as dimensions and angles of the crystal elements. 
Attached are some images of a preliminary test on C.leptoporus to validate the approach. Coccolith interlock quite well to form a full coccosphere. 

Does anyone know were we can find such morphological data? 
For example: angle of kinks, angle between distal shield elements and the plane of coccolith, space between proximal and distal shield, width of tube elements, ecc, ecc 

Do such data even exist? 

Thank you in advance for any help! 

All the Best, 
Fabrice.
