Grab Bag Noun: Sink
For my grab bag object I got sink, and after seeing that I instantly thought of a sink in the bathroom of my parents’ house, so I modeled this sink off of that design. There would not be enough room for all of the plumbing if each door led to an actual cabinet, so it should be noted that some of the drawers are just covers and nothing more. As for the creation of the model, I started with a brown rectangle and first added the cabinets, as they were extremely simple, just requiring a few more light brown rectangles with silver spheres for knobs, and a wooden divider in between the left and right side. After this I focused on the actual sink aspect, creating a white half sphere, duplicating it, putting a hole in the brown rectangle, and then duplicating it, scaling it down slightly, and putting a hole in the white half sphere so that the white half sphere would both fit seamlessly within the brown rectangle and have a hole to create a basin for water. Creating the nozzle of the sink was the most challenging part, and it was difficult trying to find shapes that would allow for a pipe design with curvature. I ended up using a combination of three shapes, those being a cylinder, a torus, and a ball handle for the knob to change water temperature and gal./min. The only thing left to add after that was the drain for the sink, and I wasn’t sure exactly what shape to use for the hole in the drain, so I chose something that would receive water from most angles while having jagged edges; a star. I made a half sphere and scaled it to be much smaller than the basin, as it only needed to be big enough to collect water and allow it to flow into the drainage system. I covered the hole with a black circle with the star hole in it.

Printing 1 of my 20 Objects
For my print I decided to go with my snowman, since it has a spherical design, and it came out better than I expected. The support was left on the bottom acted as a nice stand and wasn’t obtrusive, so I left it on.
Moving Part
(1/29/20) 
For my moving part assignment I decided to alter my sink that I made originally to have moving drawers and a door for the other cabinet. I increased the scale of the print so that the faucet would actually print and the door hinges would print as well. The problem with the door was that its hinges were still too small to support the door and came out essentially as 2 cylinders connected to the side of the sink, that easily detached from the door, hence the glue. The faucet was also too small to support itself, so I used tape to replicate the hinges on the door and to keep the faucet somewhat upright. The drawers in the sink on the other hand were much more successful. The first time I attempted this print they got stuck and barely printed at all because I printed the model with the drawers already within the sink, so this time I printed them separately from the sink, and they came out much better.
In Class Challenge
For our in class challenge, Carly and I decided to take a piggy bank with a ram head and a Yoda model and merge the two by cutting off the Yoda head and attaching it to the piggy bank body. We then added shades and covered the Yoda jaw within Tinkercad to complete the build.
Final Tinkercad Project
(2/5/20) 
For my final project, I decided to make a nutcracker with a movable jaw that will be controlled with a lever that goes through the head. I’ve created the body for the nutcracker so far but I haven’t started on the actual head and jaw yet, as that is the most difficult element of the nutcracker. (2/12/20) 
I was struggling with creating a head with enough detail to be considered an actual nutcracker, but after participating in the in class challenge I realized that I could go to Thingiverse and find a nutcracker, then cut off the head and scale and attach it to my build, making sure to include a whole for the movable mouth piece. I put a wedge to act as a fulcrum within the mouth area, and printed a rectangle with a half circle to act as a mouth and a whole to fit within the fulcrum and allow for movement up and down, thus completing the actual purpose of the print. The actual print was successful on the first try, though I had to print the nutcracker out sideways and peeling off support was more difficult for this than for any of my other builds. The movable mouth piece failed to fit perfectly the first time so I remade it and scaled it a little smaller than the first one, as can be seen in the final print by the alternate color.
Fusion 360 Ring Project
(2/18/20) 
For my ring design, I took a clip-art black and white template of some piano keys, a violin, a baseball, and a soccer ball. The actual imprints of the templates looked nothing like the templates and I had to add a lot of texture within the ring to assure that the thickness would actually print.
