This is a classic cornucopia STL for 3D Printing. This may be challenging for some printers, but it is indeed 3D printable. It may require a little skill with slicing.
We had this model commissioned for the festive fall season. This can be 3D printed as a fall décor or Thanksgiving piece. This would look great with wood PLA + it wouldn't require much finishing in that case.
Commissioned company is ILLU.
