I decomposed the parts into several layer, the inner and the outer parts.
the inner parts I tried to make it look like more of a sharp eye like shape and the outer parts as a more round and less sharp shape. Within the model the eye itself was created using create form and creating a sphere then cutting so it would fit within the model. The eyelid above the eyeball was also created using create sphere than cutting in about half then cutting it again with some thickness across the top.
The tool that I used the most was probably the complete sketching tool and sculpt.
sketch helped me create the basis of my model and sculpt helped me make smaller adjustments and big adjustments. I didn’t use sculpt that much because, most shapes I created could be made by either rotating or extruding then modifying them using cut, thicken, join, intersect and fillet.
another tool that I used was editing tools such as extrude and combine vertices. combine vertices helped me create the outer round part. when I created the outer cylinder it created itself in a weird shape where the outer parts were not joined together, creating a shape that would not be processed and create itself as a printable model. The join vertices tool helped me fix this by joining the vertices on the inner side and also helped me create the part where the triangle is in the inner circle.
a challenge that I faced was when I tried to make the several layers within the actual model itself. I had to thicken every individual part and join each part as a component and ultimately join them altogether. the other challenge was that an error kept popping up after all the components and bodies had been completed.
another of the hardest challenges that I faced was creating the tube shaped parts on the top I used the spline tool which I had used to create the axis of the balance to create curved lines on top of the actual model then used the sweep tool in order to create the tube like shape.
Using the concept of elastic force in order to wind up a wheel simply by turning the wheel. using the elastic force of either a spring or rubber band and the pulling force of a weight in order to create a toy that can be used to teach physics and converts energy.
the principal of storing energy is similar to that of a rubber wind up car. However the method used to create the potential energy is different from that of a wind up rubber band car.
using the pulling force of a weight and the elastic force of either a rubber band or spring, store kinetic energy and release it by putting it back on the ground after spinning it.
