Homework 6

Part 1: Making a 3D printed ring:

This was my first time 3D printing, so I wanted to make a simple design that allowed me to explore some of 123D Design's functions, while also ensuring that the print would be successful and feasible in a short amount of time.

Here are the sketches I based my print off of:

The ring is designed for my index finger, which I measured with calipers for sizing. My finger's radius is 8.35mm, so I scaled the ring with two sizes: 8.35mm and 9.5mm. The 9mm is ultimately the ring that fit. Making both designs in 123D Design was simple, and familiar as I've used SketchUp casually in the past.

After printing both rings, and finding that one fit, I reprinted the larger one. On the second round of printing I used a resolution of 0.1 instead of 0.2 for a cleaner finish.

I didn't have the chance to print an ornament, but I will add it soon!

Part 2: Laser cutting a name tag

Tasked with making a simple name tag, I wanted to experiment more with rasterizing.

Here is the final Illustrator file I used. In the initial versions, the fonts were a dark gray, instead of black and white.

To test how the black background of the top half would look, I tested the cut with cardboard. Next, I laser cut econowood with the same file, but there was not enough contrast in the text to be very readable. As a result, I edited the font colors for the highest contrast.

Here is an image of this progression:

Part 3: Turn in your Arduino shield

Here is a link to my Hackster project describing my process: link

Part 4: Make 3 low-fidelity prototypes of the mechanics of a remote control car

Here are my preliminary sketches for the low-fi prototypes. Each is designed with the requirements of having to move forward, turn left and right, and park.

Pictures of the prototypes coming soon!
