Airhorn

After seeing a video on youtube about an airhorne made in wood (search for 'obnoxious air horn'), I decided I would try and print one myself from the same approximate measurements.
After finding thing 2859 and finding it to be inadequate and not properly designed (middle tube should protude a little from the outside edge, and the hole in the side should have been included in the model) I decided to crank one together myself.
