Customizable Mini Siren

thingiverse

This is an innovative whistling device that produces extremely loud noise, specifically designed for the #MakeItLoud challenge. Initially, the design produced 97dB in its original size; however, with this revised version, you can easily adjust the sides to create varying tones ranging from low to high pitches. Print Settings Printer Brand: Up! Printer: Up Mini Rafts: Doesn't Matter Supports: No Resolution: 0.2mm Infill: Any Notes: It's highly recommended to print this design at a resolution of 0.2mm or higher to ensure seamless fitting of the components. Post-Printing Assembly Following printing, you need to assemble the body piece, lid, and two propellers. Insert one propeller into each side of the body and add lubricant - I personally used vegetable oil - before snapping on the lid. Ensure both propellers rotate freely; if necessary, lift the lid slightly to adjust it for proper functioning. In my case, the left propeller failed to spin initially but functioned perfectly after adjusting the lid. Design Development Background Inspiration struck while browsing Thingiverse, where I discovered The Orange Screamer (http://www.thingiverse.com/thing:455093). Rather than remaking or remixing this design, I aimed for a distinct creation and created my own concept, leading to multiple prototypes. The first attempt was unsuccessful; the second one lacked originality. Ultimately, the third prototype emerged as a new, distinct design rather than a modified remix, making it eligible for entry in the contest.
