Final Assembly: Questions?

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
