Fully-glycosylated full-length S protein model (glycol groups removed) from 6VSB_1_1_1.pdb found at: http://www.charmm-gui.org/?doc=archive&lib=covid19.

This is the OPEN conformation of the S-Protein which binds to the ACE2 receptor.

This model was generated by using computational methods to fill in missing regions from the structure found in PDB 6VSB.

The PDB was opened in ChimeraX, exported as a .glb, converted to .fbx in Blender, then brought to Pixelogic ZBrush for decimation and export to STL.
