Intro: Christmas Rail Car 2
This is rail car number two in a series of ten.
This 3D printed train car (plastic wheels, axle and bed) fits O gauge track and opens the door to one of a kind train sets. The hexbug (available from amazon.com) runs around inside the car while the car runs around the track.
Print the 3D parts, then insert the wheel/axle assemblies into the rail carrier piece.

Set the bed on the posts which are part of the rail carrier.
Glue the end caps to the top of the posts. The carrier assembly should be able to rotate freely.
Add the bed ends to the car to guide the hexbug. Put it on the track and let it go!
