Here’s a tutorial for Lightwave 3D that works pretty well in Blender. The changes we needed to make while following the tutorial were: Creating the first “Platonic” was done with a 3 sided cone primitive. Pages 2&3 needed to be done by a combination of merging vertices, collapsing faces, and Ctrl-J to rebuild some triangles into quads. To create the seams, each sub-section was extruded in place, and scaled out from the center of the ball individually. The original tutorial can be found here...
