Fracas Flinger (Fart Gun)

prusaprinters

<p>This is a tool to generate sounds. It uses an Adafruit sound board with a 2W amplifier built in. The speaker is placed in a funny cone shaped "barrel". The unit is activated using a trigger, sort of like a pistol. You can load whatever sounds you want via the same micro USB port you charge it with. I left enough room for a small 500mAh battery in the grip.</p> <p>How about cat or dog sounds to confuse your pets? Of course, fart noises are always funny. The possibilities are endless!</p> <h3>Print instructions</h3><p>I basically print everything in PETG but have provided PLA based GCODE files using the normal print settings I use. I also provided a version of the frame which includes molded in corner brims in case you want to produce that in ABS or something that has a difficult time not warping.</p> <p>You'll need to include supports on a few of the parts or experiment with changing orientations. I considered printing the barrel mounts vertically but never did. That could cut down on supports needed considerably, but I haven't tried it. The speaker cradle and barrel have curved overhangs so you'll need to support those for sure or just cut out the straggling bits, I suppose.</p> <p>I used M3 and M2.5 socket head screws throughout. There aren't many. To be perfectly honest, this was a quick job, but people seemed to like it pretty well, so I wanted to share it. I have a slightly older version over on Thingiverse, simply called "Fart Gun". It's the only one that is intended to be printed and make noise.</p> <p>The stuff I used to make this toy are:</p> <p>Audio FX Board 2x2W: <a href="https://www.adafruit.com/product/2210">https://www.adafruit.com/product/2210</a><br/> Lithium Ion Battery: <a href="https://www.adafruit.com/product/1578">https://www.adafruit.com/product/1578</a><br/> LiIon/LiPoly Backpack: <a href="https://www.adafruit.com/product/2124">https://www.adafruit.com/product/2124</a><br/> Speaker: <a href="https://www.adafruit.com/product/3968">https://www.adafruit.com/product/3968</a></p> <p>There are two types of switches needed.
