Pinewood Derby Car Shell

This is a shell to fit over a standard pinewood derby wood block. It is completely within the standard requirements for pinewood derby entries. It is a derivative of the "ActionCar pinewood edition" (thing 58010), with a number of changes: The wheelbase has been changed to match the distance between axles on the standard pinewood derby wood block. The profile has been thinned down to trim weight off of the printed part of the vehicle. Two recesses in the underside accomodate tungsten weights (fits the official cylinder-shaped weights). There are large differences now between this and the original ActionCar (thing 249), but the heredity is still visible. The wings3d file is included, and contains both the car shell model and a model of the pinewood derby block and wheels.
