I didn't really sketch any designs on paper, because I really had no idea what I wanted to make, so I just started playing around in grasshopper using graphmapper to make cool shapes until something caught my eye or I got an idea. I eventually landed on this shape, which I felt I could turn into a cup/mug or something like that.

Here is my moodboard for my Shapeways project. I want to make a cup/basket/vase or something like that, because I feel like you could use graph mapper to make cool shapes liek that.

I then baked the shape into Rhino where I capped it, flipped it around, and cut a hole into it using Boolean difference in order to give it an interesting cup/mug shape that I will continue to work with and improve upon for now, because it is sort of just a rough idea for now.

Tried to get voronoi pattern, but had some difficultiies with it.

Samu was able to help me alot to flow the voronoi pattern along the surface of the cup. At first I had a lot of difficulties trying the flow along surface command in rhino, but I ultimately was able to do it through my code in grasshopper. However the problem I still had was making the curves 3d instead of 2d, because they wouldn't show up on my print. I tried bollean unions, differences, sweeps, and extruding the curves one by one.

Had to do a bunch of boolean differences and extruding curves in Rhino, howver, there were many holes in the cup, and I did not want that, so I had to find a way to adjust that. I had also flipped the cup around again, because I ultimately ended up deciding it would look better that way. 

Here is my final design for my cup in Rhino. I just added the one of the shapes I made underneath the Voronoi pattern to get my final shape.

I made my Rhino file an STL and uploaded my final design into ultimaker, so this time, it does not have any holes and is now good and ready to print. 

This is my printed prototype for my cup. It is smaller than my actual print will be, but at least it is printable and work! I had a sligh tproblem with this design being capped during the print, but Samu was able to help me out with fixing that issue.
