Ayna and I came up with an awesome design for a 3D object with a moveable component.  We created a hamster on a wheel intending for it to be able to move around the wheel (even after 3D-printing it out).  We then placed the Hamster on a "T" bar, and implemented a track that the "T" bar was encased in (note: see Figure 3) .  Unfortunately we had a few problems....

-If you look closely, we created the track by using the "pull/push" tool and dragging the new wall…
