Portable Airhorn
Description
<i>Update 29-04: I have added the <a href="https://www.thingiverse.com/thing:5997332">Pitch Changer for Portable Airhorn</a></b></i> This little powerhouse knows how to produce a sound that will scare you. Very easy printing. All parts can be printed without support. I printed them with 0.4 nozzle and 0.2 layer thickness and 15% infill. For the small horn I used a brim of 2mm, but it can be printed without brim. Print all as positioned in the STL's. Simple assembly without glue or rubber bands.
