v30: v29 remix with source files

youmagine

So Joseph Zisa might be unwilling to share CAD files of his v29 whistle or he simply doesn't have them. I've decided to create my own based on his design, taking only the general idea into consideration. The concept is good. This one was created from scratch. I used Joseph Zisa's idea as a starting point but gave it a unique shape and omitted internal ribs. This makes printing much faster without compromising function - ideally, you shouldn't print this model without infill. Printing with less infill will also result in significant cost savings since thermoplastic can be pricey. Additionally, the reduced weight allows for easier buoyancy when printed with less material. The excess weight from redundant ribs on v29 is eliminated, making it a more efficient design.
