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.


Step 1:

Print the 3D parts, then insert the wheel/axle assemblies into the rail carrier piece.

Step 2:

Set the bed on the posts which are part of the rail carrier.

Step 3:

Glue the end caps to the top of the posts. The carrier assembly should be able to rotate freely.

Step 4:

Add the bed ends to the car to guide the hexbug. Put it on the track and let it go!

<p>nice :)<br><br>smaller bed ends would have been nicer to increase the hexbugs movement range :)</p>
