Introduction: Christmas Rail Car 4
This is rail car number four in what (I hope) will be a series of ten, one published every two weeks until Christmas. This O gauge car (wheels, axle, coupler and bed are all 3D printed plastic) is part of an active train.
Print the base, two sets of wheels and the propeller.
Print files can be found at:
Insert the wheels.
Push a pin into the top hole.
Place the propeller on the pin.
Bend the pin so that the propeller will be facing forward when the car moves.
Get up some speed and the blade will spin!
