This is the Waco Series S (Custom Cabin) aircraft.It was the immediate pre-war (WW-II) preferred American Civilian Trainer. It became the bush-plane that opened the Canadian north before the advent of the venerable Norseman of Beaver aircrafts.
It is contained in redundant file structures from .blend , .STL. .3MF and gcode for 1:120 scale PLA in pieces set up to fit on a standard 3D print stage (recommended PETG filament gives slightly better results compared to PLA)
3D display formats also included are obj/mtl, fbx and gbl. You may reslice for different sectioning of the model, different filament type or a different scale. Best guide is obviously to read your printer and or Slicer docs
A 3D display of the file is available to view and of the models for sale here at the portfolio page on my main Website (
