4-key fagottino, ANONYMOUS (11), ca. 1750–1790
FT40 is a four-key fagottino made out of brass and maple by an unknown maker in the second half of the 18thcentury, located in a private Swiss collection. See more details and pictures of the instruments on this link.
After the X-ray-CT scan was made, two 3D-models of each original fagottino were created using 3D printers. The metal keys and the bore were printed separately using different 3D- printing techniques. In this particular case, the metal saddles where the keys are mounted were recreated and printed in nylon directly on the surface of the instrument, as seen in the following photos.
The two different 3D printed prototypes are as follows:
Some corrections were made for model II, such as filling a hole that was present at the top part of the wing joint for unknown reasons, as seen in the following image.
