Concept: Originally I wanted to create an ear cuff, but I moved on to a headpiece for more surface area to maintain the concept of a curved adornment. The derby hat made me realize a single thing piece of plastic is capable of carrying a high volume. The feather crown encouraged me to use a thicker band but after some modeling, I decided to go back to a thin band. The second crown with candles inspired me to use rectangular and vertically standing shapes. Seeing the arrangement of the crowns and hat helped me decided my own arrangement of shapes.

Techniques: To begin my headpiece, I created a curve and extruded it for the base. I then moved on to what I believe was the most challenging aspect, the threaded circle. I made a cap and bottle-like design using curves as guides for my spiral which I used "Sweep rail 1" to create an inner and outer thread ensuring I selected "Roadlike" each time. Using "cap" I closed the two threads. I then boolean unioned the threads to shapes creating using "revolve" on two rectangles guiding the spiral.

I then boolean unioned the top shape to a thin cylinder to be the "topper"; the bottom one to the band extruded curve. I then moved on to my snap-fit joints. I created one cube, then created a prism using polylines and boolean unioned them once it was extruded. I then used boolean difference on another cube to create a piece that could snap onto the first. I then boolean unioned the prism cube shape to the band. (2x)

Lastly, I created two spheres, one slightly smaller than the other. I then created a rectangle to slice through the larger sphere using boolean split. Using boolean difference I made an indention within the bigger sphere using the smaller sphere. I then created a curve which I extruded, to cut out some of the sides of the larger sphere to create a socket using boolean difference. I then joined each sphere to a cylinder using boolean union. Finally uniting the socket to the band using boolean union. (2x)

Materials:

    Keyshot: I chose a white plastic in Keyshot for all my pieces because I wanted them to look like one piece when assembled. I did not change the lighting as the setting showered the surface as I desired. For the environment and Image 08, I chose a portrait by Alyona Grishina, who allows the reuse of her work. The black and white coloring of the portrait made my piece seem more natural. Grishina's subject's face is very symmetrical and so I really like my headpiece on his face, it seems to compliment it. 

    Post-processing: I had to sand down my snap joints so that they would fit into each other. I used a little bit of force to slide them all the way through. My ball and socket joints fit perfectly so I didn't have to do any post-processing on those pieces. Unfortunately the method and material I chose to print in made my screw joint unusable. The additive technique was done adding the material moving up and down and therefore the curves that go around left to right didn't come out properly. I sanded down the piece of the thread on the headpiece to try to screw the cap on but unfortunately that also sanded down the curves of the thread. Overall I was happy with the look of my headpiece but I would use a different technique in the future when printing threads.
