Devil Cube Finished + R2D2 Progress

So I finally finished the great cube challenge. Surprisingly enough it only took the first 10 minutes of class, today. This is how it turned out.

Also the weird shading on the sides was fixed by using Normals > Set Normal Angles. Essentially it fixes the normals of the vertices of the object.

Also I have made more progress on R2D2. Currently I am working on the coupler for the leg. This is what it looks like now.
