Air Horn d352|17
When i saw the YT videos of DIY Airhorns from PVC-tubings i thought that should be easy to print so I planed to make a 3D-printed AirHorn.
First I thought i would need a rubber membrane but turns out a three 90µm layer bottom works perfectly. So it was possible to further simplify the design by incorporating the valve into the membrane and print everything at once. In this early version i made the valves center part trimmable but this could be a also a strurdy connection.
Material is PET-G printed on Polyimide film (Kapton). The heavy stringing is caused by higher temp to fuse the bottom well (and not perfectly dry filament)
(the microphone seems to auto compensate the volume level - but this is annoying loud)
