Lab 3

Lab 3: Part A
Description of what I did:
     For part A of this lab I designed three objects in Rhino that I was interested in making out of paper. For the first two objects, I modeled them as surfaces in Rhino and then converted them to meshes and used the reduceMesh command to simplify them. I then used the meshtoNURBS command and unrolled them. To create my third object I unrolled it using the same steps, however I first modeled it as three separate pieces in order to put it together with more ease. For objects two and three I also cut up the unrolled mesh to create simpler patterns to follow when putting the objects together with paper.


                                  First Object                                  




                                  Second Object                                  


                                  Third Object                                  





Lab 3: Part B
Description of what I did:
     For part B of this lab I chose to make my third object (a hat, as shown above) out of paper. I printed the design onto a couple sheets of printer paper and cut it out using an x-acto knife. I then folded and tapped together the object to create its 3D form. My printed hat is not to scale, but if I wanted to print the pattern onto larger sheets of paper it could be made to scale. The final product is shown below:




Lab 3: Part C
Description of what I did:
     For part C of this lab I modeled two function objects, an end cap for a pencil's eraser and the grip that fits on the end of the pencil, and my real life object from Lab 2 which was a pen. I modeled my two functional objects in Rhino using the circle, line, and loft commands and made sure to model them to scale to fit onto an actual pencil. The 3D print of the objects had some printer inaccuracies, as half of the print was more melted than the other and made the cap to the pencil not completely fit onto the end pencil grip. These objects and their 3D prints are shown below:
