It’s becoming increasingly evident that 3D printing is a go-to technology for all things cosplay. Just look at all those wonderful Iron Man and Samus suits all over the web. But if you’re looking to cosplay someone with actual human clothes, 3D printers are perfect for recreating those cool props that make or break a good cosplay. And the undisputed masters of electronic cosplay props are the Ruiz brothers over at Adafruit, who have just shared their designs for another great prop: the syringe Little Sisters carry around in Bioshock for extracting ADAM.

If you’re looking to wreak havoc at a con in a Bioshock suit, then this is definitely a must-have 3D printing project. Especially impressive about this syringe is its simple electronic build, that enables to container to glow eerily red at the push of a button. What’s more, the project is relatively simple to complete, especially in terms of Adafruit projects. In their own words, ‘it’s geared towards makers who have basic 3D printing skills and access to a 3D printer. The circuit is very beginner friendly and easily to solder.’

Fortunately, all the 3D printable parts for this build have already been prepared and can be easily downloaded from the Adafruit page here. All have designed for large build platforms, so it might be necessary to downscale them (or to split them up into smaller pieces) using MeshMixer or similar tools. Printing itself can take up to 24 hours, so be sure to take the time for this project. The Adafruit guys recommend printing everything in PLA using copperfill settings (no support), with 15% infill and 0,15 layer height. Thoroughly smooth all layer ridges until you achieve results similar to theirs, which should also do wonders in bringing out the metallic shine.

Really the only unusual printing step in this project involves the rubber nipple on top of the syringe container. The brothers suggest 3D printing this part in TPE flexible material, but it depends on what you have laying around. They settled for Caramel Ninjaflex as it closely resembles the copperFill filament. For added effect, you might want to 3D print this component in translusent water color to allow light to pass through it.

Finally, it’s a matter of installing all the electronic hardware, consisting of a 0 mm LED, a 6 mm tactile button and an LIR2450 Coin Cell Battery to power it all. While this will take some careful soldering to put everything in its proper place, these electronics are far easier to install than those on most Adafruit projects, so few problems should occur when following the brothers’ steps.

Assembly, to conclude, is pretty straightforward thanks to a small amount of E6000 glue and a couple of screws. Really the only thing that can go wrong is that one side has received a better polish than the other, so be sure to keep your Dremel close by to complete the look. And that’s really all there is to it; it’s a remarkably simple, but utterly fun project that is perfect for a new cosplaying adventure.
