Cosplay, if you’re not familiar with the practice, is a sort of performance art in which participants, referred to as cosplayers, put on costumes and accessories meant to represent a specific character or idea, most often at conventions, or cons (like the famous Comic Con events). Many of the sources for the costumes spring from Japanese manga and anime, comic books and cartoons, video games, TV shows, and films.
Ever since Nobuyuki Takahashi first used the word in Japanese magazines back in the early 1980s, cosplayers have reached ever further to jazz up their inventive array of gear.
Now a project on Adafruit is aimed at letting you create your own set of “fire horns,” and really, what costume wouldn’t be significantly amped up with a set of fire horns?
The project is the work of the Ruiz Brothers and Phillip Burgess, and they’ve made the process relatively transparent for you to make yourself the Beelzebub of your dreams.
The fire horns in question were 3D printed in NinjaFlex material to result in a flexible, wearable set of accessory horns sure to draw some attention from the squares. And the fact that they’re printed in the soft material means you’re unlikely to poke out anyone’s eyes as you thrash across the dance floor with all your friends at late-night con raves.
Made as a hollow shell, the 3D printed horns allow for the easy fitment of a strip or ring of LED lights within. The tutorial includes complete instructions on how to create 3 different types of horns.
You can find all the parts to print out your own set on Thingiverse (the STL files are also posted on Adafruit), and if you manage to get your hands on the correct parts like a Trinket, NeoPixel strip or ring, a slide switch, a JST extension connector, and a 500mAh lithium polymer battery, you just need a little skill with a 3D printer a soldering iron and some heat shrink tubing to take your costume to the proper level of awesome.
While the Adafruit post doesn’t specify the total cost for your new horns, does that really matter? What are a set of fantastic, LED lit 3D printed horns worth, anyway? Priceless…
Will you print yourself out a set of these excellent LED lit horns? Let us know in the 3D Printed LED Lit Cosplay Fire Horns forum thread on 3DPB.com. Check out a video of the lights in the horns, and some more photos, below.
