I went back into Blender and scaled down the stairs so the water droplets would be larger and less detailed, in the hopes that it would yield a cleaner and less fragile print. While I did really like the definition of the other design, I think this works better for printing purposes. I added a bigger loop, as well. It seems to pass most of the Shapeways requirements, except there are warnings on the loose shells and wall thickness sections, but I'm hoping those shouldn't be too big of an issue.

Back in Rhino
In Rhino, I added a piped curve so I can use the design as a pendant or earring. I also designed an axel sort of thing in the middle of the column so if printed correctly, it can spin because I thought that would be fun. I also had to go in an manually delete all the little droplets that would print disconnected from the larger piece. I plan to do a test print at Lick today and test that it works for shapeways.

Water effect in Blender
Using Blender's liquid simulation I added a water splash running down the stairs. I imported the stairs as an STL to Blender. At first, the water was just falling through the stairs, but then I realized I needed to set the stairs as an effector. Then, the water would hit the stairs, but it wouldn't follow it's path, so I had to create a nurbs curb forcefield for it to follow. It's still not exactly what I wanted, but everytime I experimented with settings, I would have to wait around 45 minutes for everything to bake again.
Unfortunately though, it only half-worked. The shape of the droplets still only formed in squares around the stair steps and looked really dense.

Trying to add the kinetic droplets to the bottoms of the staircase steps
I plugged in the surfaces that make the bottom of the steps into the plane input for the kinetic droplets. However, there is a difference between the planes and the surfaces, so the evaluate surface node ran into an error. I replaced it with an evaluate box node, which did not run an error.

I'd like to do something inspired by water because the roundness of droplets is hard to achieve w/o wax casting. Since 3d printers can print almost a perfect sphere, I think that'd be cool.

Right now i'm leaning towards making earrings or maybe a pendant, but I'd like if there was some aspect of movement, like a rolling sphere or pendulum or something. I'm not exactly sure how I'm going to fit in the parametric aspect yet.
Elk topography of SF
The ELK add-on is pretty cool! I had some trouble installing it and briefly had an error about not being able to open external files, but I just deleted and added it back to the components folder. My computer would crash when I tried to add the Mesh Reduce component. Also, I couldn't bake the roadway version.

Paneling with surface morph tutorial
Both of the above/below tutorials were pretty straight-forward but I feel like I still don't completely understand all the domain components. I thought the neighbours input of the vornoi cell was really interesting though.

Voronoi Sphere Tutorial
I tried to change the color of the sphere and keep the weird shiny texture, but I think the texture was just a result of the mesh colors thing.

Grasshopper Mini Challenge with Sean
We chose to explore the voronoi and construct domain2 components!
The voronoi components creates a voronoi diagram based around inputted points and a set boundary. A voronoi diagram creates a pattern of cells that divides up the plane. Each cell's interior is made from points that are closer to a particular intersection point than to any other point of intersection. The pattern can be found in nature. In Grasshopper, the voronoi component is frequently used in conjunction with the populate components that populate an area with an inputted number of points at random locations. The voronoi pattern is built around those points.
In our mini challenge, we used the voronoi component to create the holes in a twist cone shape. We customized the voronoi cell pattern by using a Weaverbird add-on to round out the cells. We also created a line that could control the areas where there would be "windows" and what parts would be filled in. We then could also control the arrangements of the voronoi cells with a curves graph. We learned how to do this through a tutorial.
The construct domain2 component takes two U and V inputs and outputs a domain that dictates the area from where the U and V go (like u:{0,5} v:{0,5}). This creates the boundaries or range that can be visualized as a a square with corners at (0,0), (0,5), (5,0), and (5,5). The construct domain2 component can be used to set boundaries for a voronoi pattern, for example.
In our mini challenge, we used the construct domain2 component to construct a square boundary based on the UV from our twisted cone shape. Then, we could apply the populate 2d and voronoi components to create a pattern on the 2d square boundaries of our domain2. Finally, we gave the pattern thickness and applied it to the cone to create our final creation!

My design for the tessellation basics
I extruded a hexagonal and triangular tessellation on top of each other.
Experimenting w/ extrusions
I extruded a heptagon with filleted sides. I tried recreating it using the loft component, but again it rendered only as the curves in Rhino. (pictured below)
loft component still not working
it shows up as a surface when I select the component in Grasshopper but doesn't bake correctly
5 ways to make a cylinder w/ Grasshopper
I don't fully understand the loft component; it appears to work in Grasshopper before baking but never renders properly.
The pipe, cylinder, and extrusion components make sense to me.

a simple torus! (I had to download the Lunchbox add-on which took me a long time to figure out because there was no Mac version)
a polar array of spheres where I experimented w/ the angle, planes, etc. initially wanted to trim from torus but I didn't like the way it looked
3D Printing Challenge w/ Lucas and Sean
Joints and high infill requirements
ball and socket joints for tentacles
dense infill in body
A challenge and a wish:
Printing the legs was difficult because the snapping part of the joint didn't appear Simplify3D slicer, despite lots of troubleshooting—I ended up using the Prusa instead and doing a lot infill-removing.
I wish we could have made the joints more sturdy and printed out the body which had a more smooth transition between the legs and body, like a real octopus. I also wish we had time to add a face to the octopus.
