Còi PROTEST (PROTEST Whistle)

PROTEST Whistles

PROTEST Whistles are two-note whistles designed for protestors. The sound PROTEST Whistles make is sharp, resonant, loud and above all: distinctive. A distinct sound makes it possible to locate other group members in the chaotic visually cluttered, crowded, noisy protest environments. When you are protesting you’re are not alone. The sound is your signal. Think of it as an aural equivalent of a large, distinctive banner held up high for all to see.

Alternate  Dual Tone Whistles

Democracy is advanced citizenship. Time to get over being shy. Step up in every way possible. But, if you’re still uncomfortable with this whistle’s visual messages it is also available in another form. a designer whistle that uses no words. Just designs, shapes and forms. Link coming soon

Messaging

Besides the sound, PROTEST Whistles show off a visual message. These whistles are imprinted with different words/messages. Words or symbols are de-bassed into the top and bottom whistle surfaces that are included with this set. A blank PROTEST Whistle can be customized with your choice of words/message using the add text function available in Prusa Slicer, Bambu and Orca Slicers.

Whistle Design

These whistles are designed for visual customization and a distinct, rich, and intense sound. They generate a full, resonate sound whether you’re blowing hard or soft. As you blow, air accelerates as it moves through the aero designed input tunnel to increase air pressure before entering the sound chamber. As air flow is splits across the new fipple, turbulence is dramatically increased to create the  sound + overtones that form and  resonate inside the smoothed and directed sound chamber. Finally, air and sound exit quickly through the whistle window. Weird explanation, I know. But that’s what’s going on when you blow this whistle.

Sound and 3D printing design of these whistles was developed through dozens of prototypes made over several weeks using a large variety of 3D printers.

Why Whistles

This whistle is designed for protesters. It makes two tones. Other single tone whistles for vulnerable groups warning of the presence of ICE are listed below.

You and Your Printer Can Help

As a 3D printer owner you can help by making lots of whistles. A 3D printer is a machine designed for easy manufacturing. Use it.

• Make large quantities for local organizations who can share them in mass

• Bring lots of whistles to local events and protests to share with fellow protesters.

The whistle is tuned to B and C# (depending on how hard you blow of course., The tones are distinctive and deliberately a little uncomfortable. Because of the new sound chamber, window and fipple designs, the sound is full for a small whistle and very intense. Warning: it is 118 - 120db so be careful with your ears. Unlike many 3D printed whistles, this one works under both low and high pressure blowing. Finally, if you follow recommended print settings, it should print well on just about any of 3D printer. Over 40 prototypes and lots of testing

The whistle is small and has a horizontal lanyard hole so it rests flat when worn. Printing takes about 7 grams of filament and around 20 minutes to print.

Printing models this small requires different printing techniques. Please read recommended print settings.

Notes:

This is a very small 3D printed item often printed in large quantities. Successfully printing small things in quantiles require different methods, settings, and techniques than average medium to large 3D prints. As a designer, I’ve created a lot of models for 3D printing that are very small. Around 20,000 so far. So, I’ve a few recommendations about printing small items that could be helpful.

Printing

• Printer's I used: for testing Prusa XL, Prusa Mk4s, Prusa Mini, Bambu X1C, Bambu Mini

• Rafts: No

• Supports: No

• Resolution: .15 or .16 depending on your slicer. The result is crisper detail in internal sound creating parts.

• Infill: 15-20%

• .4mm nozzle. Smaller nozzles are not needed.

Overhangs

This whistle has an overhang which can cause problems. If your retraction settings aren’t perfectly tuned the unsupported top inside entrance can sag a bit. There are two solutions to this. Turn on supports and paint on support for just the inside top entrance of each whistle. The area is small and and is tricky to get right. The easy solution is to use the CAD created custom support versions created for these models. Check the photograph. Look for “sup” that’s added at the end of each file name. I've included model versions without support if you prefer them.

Settings

Though the whistle models are tiny, but they have a lot of mass for their size. Much of that mass is vertical. That means they can easily get knocked off the plate. So, I recommend the following. 

• Use smooth printing plates if possible, not textured plates. Textured plates are fine when printing small things in PETG. Not so much when printing small things in PLA. Smooth plates are often the best solution when bed adhesion issues are likely.

• When printing items of this small on a smooth plate I always clean it and use a thin layer of some sort of plate fixative and refresh it every few prints. Various dedicated 3D printing products work fine but so does a thin layer of glue stick. Serious and professional 3D printer users know this and always use a fixative as insurance when printing small items.

• Slow things down. Set print speeds slower. I slow down outer walls and particularly the first layer. I run first layers at 30mm. Small contact area models really benefit from a perfect first layer. 

PLA

The model was designed to be printed with inexpensive PLA filaments. You can use up left over spools to print lots of whistles with whatever filament you have around. That way you can donate lots of whistles. Best to stick to regular PLA and not use filaments with added materials. IE carbon fiber, glitter, etc. Avoid silk as these filaments are weak. Be careful with matt filaments as they can also be weak. Because of the print details it's a good idea to dry your filament before printing. Wispy strings inside the whistle can cause whistles to not work and other problems. If using PETG which is more prone to whispy stringing, drying before printing is even more important.

The included 3MF files include recommended print settings. Note that Prusa, Orca, Bambu and Cura slicers can open 3MF files from inside them.

Print Test

Print out a single whistle to make sure it works as a whistle before committing to mass quantities at a time. What you're aiming for is a full, resonant sound at low and high pressure blowing.
