3 Fun Horns

thingiverse

These are 3 horns just to have fun and make a lot of noise. The largest horn produces a lower tone like a fog horn, while the smallest horn produces a higher tone. I adapted dougfeig's "One Piece Deafening Horn" (thing:831868) design to have a more aesthetic horn shape and to include two rings to keep the rubber band in the correct position. WARNING: Do not point these horns at another person, they really are deafeningly loud. Stretch either a balloon or plastic food film (Saran Wrap(R)) over the mouth piece and hold in place with a rubber band as shown in the picture. Trim the baloon or plastic wrap to clear the side blow hole. A rubber balloon gives a deeper tone while the plastic wrap produces a higher tone. horn dimensions: horn_tiny_160129.stl: 95 mm tall by 90 mm by 90 mm horn_small_160127f.stl: 180 mm tall by 90 mm by 90 mm horn_big_160129d.stl: 280 mm tall by 130 mm by 130 mm four ANSYS classic APDL scripts were used to create the .stl files mk_horn_tiny_160129.mac mk_horn_small_160127f.mac mk_horn_big_160129d.mac nice.gsav ! view orientation file ansys_2_stl_append_130131.mac !
