Whistle V29

The Famous V29 Whistle. Annoy your loved ones Print Settings No Rafts: No Supports: Resolution 0.2mm  Infill 100% (any is fine but may effect durability) Original from jzisa: The MakeItLoud V29 got its name because it is the 29th version I designed for this challenge. It is a survival whistle that is a completely original design. I designed it to be rugged, easy to make and carry, have a great design and most importantly be very loud. It is designed to be able to get you noticed in all conditions. For ruggedness testing I spiked it into the pavement as hard as I could repeatedly. Then I ran it over with my car twice. Finally left it in a glass of water for two hours to make sure that it would not sink and would drain and whistle immediately after taking it out. It still whistles. The design is meant to look as clean and simple as possible while still looking like a whistle. It was also designed to be easily gripped with thick gloves or cold hands. It has a raised lip on the bottom and grips on the top to allow you to hold it securely in your mouth even if you are blowing as hard as you can. There is a hole in the back for a key ring or lanyard so you can wear it around your neck or attach it to your zipper or keychain. Another huge focus in designing this was to make it printable in one piece with no supports or rafting. I wanted someone to be able to print this before going for a hike or something with no assembly, cleanup, or fuss of any kind to get it ready. Just print and go! The whistle actually has two slightly different tones produced at the same time by separate chambers on either side. The two different tones alternate between amplifying and canceling each other out. This variation creates the shrill sound much like a pea whistle that is more attention grabbing and does not get lost as easily over background noise like a single tone whistle could. Unlike a pea whistle however it does not jam if blown too hard and will not freeze up in cold weather. I tested
