Under the Render section, I picked Object and for Dupli Object, I selected the single Flower model I made. The system is going to rely on my Face normals (the direction my faces are) to determine which way to rotate my “hairs”. Under the Rotation section, I first checked Rotation and then for Initial Orientation, I picked Normal. This just happens to be the number of vertices in my modified Ico Sphere. This is telling Blender that each “hair” (aka flower) is going to be associated with a vertex in my model. Under the Emissions section, I clicked Verts. I checked the Advanced box which would allow me to change some rotation settings later. I clicked on New to create a new Particle System. Once I was satisfied with my Ico Sphere, I clicked on the Particle Systems icon. I went ahead and removed the bottom half of my Ico Sphere and gave it a flat bottom. To convert my single flower into a ball of flowers, the first thing I did was add an Ico Sphere with 2 subdivisions to my Blender project. Thinking about how I wanted this to be sturdy for people to grab, I kept the petals thick and shallow. First, I made a model of an individual flower. My steps for using the Particular System were: Thanks to a wonderful tutorial video by Blender Facile, I learned how I could also use this feature to convert a single flower model into the trademark ball of flowers for the rhododendron. They are typically used for animating dust, smoke, water, and hair. I had never heard of “Particle Systems” before and with good cause. It was a Blender animation feature helped me pull off my vision. Homesick for the Appalachian Trail, I embarked on making rhododendron themed drawer pulls. It has a lot of extra features or capabilities we don’t use for 3D Printing. One of the things that gives Blender its reputation of having a large learning curve is it is geared towards animation. 🙂 Blender Blender 3D Printing by Example I’ve been known to show up from time to time. Also don’t forget to check out the Friday Night 3D Printing Community Hangouts. I will also be helping with the East Coast RepRap Festival which is looking like it will be in late June. I’ll be working on my proposal and projects for the MakerFaireNova on March 18, 2018. What’s next for me? I have a long list of videos I would like to make. If you do wish to have a copy, you can purchase the book on Amazon. YOU DO NOT HAVE TO BUY MY BOOK! I am already very happy as is. 
The book walks through four separate projects to teach Blender tools and skills. It got published last week! I decided my return to YouTube should be called, “You Guys, I Wrote a Book!!!”. Greetings All! Working with Packt, I wrote a project-based learning book to teach Blender for 3D Printing.
