Christmas Rail Car 4

About: I am an author and a maker. My current project is Santa's Shop. I'm working on a science fiction type book--more later. @EngineerRigsby

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.

Step 1:

Print the base, two sets of wheels and the propeller.

Print files can be found at:

Step 2:

Insert the wheels.

Step 3:

Push a pin into the top hole.

Step 4:

Place the propeller on the pin.

Step 5:

Bend the pin so that the propeller will be facing forward when the car moves.

Get up some speed and the blade will spin!
