Air horn

thingiverse

This is a air horn that I designed a while back, but i haven't got a chance to print it print yet. You will have to use a balloon in the back of the body in the horn body to produce the sound. When you print off all the tubes standing up so they will turn out more circular. To put the air horn together you will have to print off all the parts, then you will have to cut a circle out of the balloon and stretch it over the end of the the main body. You will then have to screw on the cap, until it is screwed all the way on. Then you will insert the tube the tube true the hole at the top until you can see the shape of the tube threw the balloon. You may have to sand down the outside of the tube to make it fit in the hole, but you want too still be tight to the sides of the top hole, to make a seal. Finely you insert the horn bell on the end of the tube, and glue it in place. Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator 2 Rafts: No Supports: No Resolution: 0.2mm Infill: 15%
