These STL files are designed to allow the user to 3D print the parts and assemble a brougham horse drawn carriage. This carriage makes an attractive coffee table conversation piece. I recommend the user 3dprint the parts in PLA and assemble the model with Testors Cement for Plastic Models (in the red tube). User may need to scale the parts down in the slicer application to ensure all parts will fit on the printer plate. Be sure to scale all parts the same percentage. For best results the user may print the body panels in multiple colors by changing the filament color at proper z-axis levels. It takes a little practice but produces good results without painting the parts. Prusa slicer manages that process very well.
