Horn for the American Gramophone Co. Type Q Gramophone, a 100+ year old music player! When my beloved grandmother passed away, she left me a gramophone by the American Gramophone Co. Unfortunately, it was missing the horn. It's been re-created based on photographs from the web and modeled in Solidworks.The STL is a surface that's offset from the outer diameter of the gramophone's sound outlet. The part is roughly 7in tall and 3.25in in diameter Set perimeter layers to 3, printing from the outside-in with 1.75mm PLA filament. Ultimately the wall thickness should be around 1.9mm. Position the part with the wide end facing down.
