Pinewood Derby Car Shell

thingiverse

The provided text describes a customized pinewood derby car shell that adheres to standard requirements while being derived from the "ActionCar pinewood edition". This shell has been adjusted to match the wheelbase of a typical pinewood block, and its profile is thinned for weight reduction. It also accommodates official tungsten weights in two recesses on the underside. The original ActionCar has undergone significant changes, but its lineage remains evident. Along with the car shell model, the wings3d file contains a pinewood block and wheel models. To assemble this derby car, first cut the block's height to 10mm and saw the front and back ends for proper axle placement. Then, print the shell with low-density fill and abundant support material since it is hollow. Finally, place tungsten weights in the recesses on the shell to meet the 5oz weight limit.
