A simple car designed in SketchUp and 3D-printed on a MakerBot Replicator 5th Edition. This print was also a test of the acetone vapor finishing: a small amount of acetone was heated over a hot plate in a sealed glass pot, with the model inside supported by four screws screwed into a wooden base to minimize contact surface area. After the model had been surrounded by the acetone vapors for several minutes, the pieces were removed and assembled using "Instant Arrow Glue" (comparable to Gorilla Glue or super glue). The attached model includes the main car body, four wheels, and two axles. Small washers were glued onto the sides of the wheel hubs to support the wheels and axles. Short segments of rubber bands may also be glued along the rims of the wheels to function as tires, which helps to increase traction and makes the model roll more easily.

Supports were a bit difficult to get off around the windows, but they may not be needed for the model at all. If there are rough edges left from removing supports, the aforementioned process of acetone vapor finishing can help cover these up.
