3-D model of Parvancorina minchami from Russia in STL format

A freely-available reconstruction of Parvancorina minchami from Russia in dorsal view (https://en.wikipedia.org/wiki/Parvancorina#/media/File:Parvancorina_species.png) was imported into the open-source 3-D creation program Blender (http://www.blender.org) and used as a reference to guide box modelling of the shield-shaped base. The file was exported from Blender in STL format and converted into a non-uniform rational basis spline (NURBS) surface (IGES format) in Geomagic Studio 2012 (http://www.geomagic.com). This IGES format file was then imported into the commercial simulation software COMSOL Multiphysics (https://uk.comsol.com/), where the raised T-shaped ridge was digitally modelled with a half torus, a cylinder, and three spheres. The final model was exported from COMSOL in STL format.
