This update includes the final two parts of the design and building of the Morris Stockyard/Feed Lot with 3D printed parts.  The video below (Part 3) shows some of the final testing that was done to ensure that the spacing between the siding and the cattle ramps was sufficient to permit a train to pass by all of the 18 ramps.  During the testing, I found one ramp that had to be moved back.  The train in the video is pulled/pushed by an Intermountain FT A/B with a few stock cars prior to beginning the next step of assembly. In this video, only the ramps have been glued to the base.  The camera (Polaroid Cube+) is mounted on the FT B unit.  The background noise is the engine plus you'll be able to hear cattle sounds from the Broadway Limited sound equipped cattle cars.

This is Part 4 and concludes the building and assembly of the 3D printed stockyard/feed lot for the layout.  It took about two weeks to design & 3D print the parts (based upon the hand-drawn plan shown in Part 1), plus painting, some preliminary assembly (cattle ramps & worker walkways), checking alignment, and final assembly on the layout.  The parts cost approximately $12 to print (does not include the investment cost of the 3D printer) and another $15-18 for glue & paint. The total project cost is about $27-30.
