These STL files allow the user to 3D print a model of a horse drawn brougham carriage. This makes a very nice coffee table conversation piece. I recommend the user print the model in PLA and assemble it using Testors Cement for Plastic Models (in the red tube). It may be necessary to scale the parts down in your slicer application to fit your 3D printer. Be sure to scale each part the same amount to allow them to fit together in assembly.
