Stellated icosahedron with 3d pen

My PET project! I wanted to build a stellated icosahedron ever since I got my first 3d pen. It took me seven years to build up to it. You don’t have to wait seven years. This tutorial shows you how to start the project today! Useful whether your goal is to make a geometry model, Christmas tree-topper ornament, or just to gain understanding of the stellation process.
Great information for artists, STEM teachers, art teachers, homeschooling parents, crafters, and all 3D pen enthusiasts.
