Week 7: Molding and Casting
Molding
1. Introduction
This week we were supposed to mold and cast something using the materials that we had in the lab. I ended up using the wax to make an oomoo mold, and then I casted my object with drystone. This week I decided to make a wheel since I am planning on making a roller skate for my final project.

Figure 3. Rough cut of the wax to take off most of the non-defining features.
Figure 4. Error in my vcarve file as I thought I had said to not remove bottom half but it was below the cutting plane apparently.
