Flat Gem 8 Facets

This is a gem I made for a costume as my first ever print! I made the exact duplicate in clay but wanted something more precise. It spent me about 10 hours trying to learn blender and create this little gem. It prints out very smoothly at the lowest layer setting on cura. It will need to be scaled up (something I haven't gotten the hang of in blender yet) Hope this is useful to someone out there!
