Fans of Nintendo’s Legend of Zelda series might be interested in the latest DIY project just published on the site of 3D printer manufacturer Adafruit. Not so long ago, the team made an impressive 3D printed version of the Guardian Robots that featured in last year’s popular Breath of the Wild game, and this has now been updated with a couple of extra features, after requests from 3D printing enthusiasts and fans of the game.

The replica robot has 6 threatening-looking tentacles coming out of its central body unit, and their motions are illuminated with an array of blue LEDS. The head is able to move freely around with the aid of a micro servo, and it has another 10 mm blue LED serving as its eye. As the head moves in random directions, with the blinks of the LED eye also randomized, the robot genuinely gives the impression of searching around for something, and we really wouldn’t want to be that something.

Two different materials were used for the 3D print job, one opaque and one translucent. The translucent filament that the details are made from allows the LED light to be diffused nicely, making the whole robot glow in a way that really brings it to life.

The Adafruit team used an Ultimaker 3 and a Sigma BCN3D 3D printer to make the parts, as both are capable of dual extrusion to achieve the lighting effects needed. CURA 2.6 was used to slice the parts for the Ultimaker 3, and Simplify 3D was used for slicing for the Sigma BCN3D. In the how-to guide, there were recommendations for a variety of other desktop FDM machines that can be used, including the flashforge creator pro, the Prusa i3 MK2 with Multi Material upgrade kit, and the Palette+ from Mosaic Manufacturing. The team did limited post-processing work as the bumpy layers from 3D printing, which would usually be sanded down, added to the weathered effect that the ancient Guardian Robots have in the game.

The more functional elements of the replica are quite complicated, with all kinds of different circuitry and some basic software coding required, but Adafruit has published extensive information on how to achieve this as well as a list of other non-3D printing tools that might be required, should you wish to emulate their achievement. One of the more interesting final suggestions for what you could do with the robot was a stop motion animation- Zelda devotees could maybe try re-enacting some of their favourite scenes from the game. Or alternatively you could just try and freak out your friends with this faithful recreation of the intimidating ancient guardian technology.
