Conceptualization
1
Working with circles and angles
1
Can be annoying.
Needle of the compass leaves a mark
Compass slides if circle is too small

3
Paper slides if not held in place
Protractors aren't always the right size

Final Assembly: Questions?
Improvement

3D Printing for Testing
Prototype "printed" to "verify" functional integrity
Majority of functionality works according to specification
Assembly only possible, well, hypothetically, so that's not good
Flimsy, due to use of Derive and dimensions
1
No obvious center point to use when using protractor
2
Optimize drawing of circles that are small
3
Reflection and Next Steps
Think things through more and fix issues
Create mechanical, non-electronic version
Iteratively follow steps to improve on product
