Portal 2 Personality Core Ultimate Animatronic

thingiverse

This is the most ambitious Portal personality core ever undertaken. Eighty-three parts need to be printed. It took me over 24 hours to design within four days. It has nearly every axis of movement as seen in the game. Game accuracy is not lacking. Twelve servo motors, two geared hobby motors and several M4 screws (5mm diameter, other screws could work) are required. The only thing left out was the actual eye; I'm designing those separately now, and you can even design your own if you'd like. The inside diameter of the eye gyro is 31.5mm. When it's built, a video detailing everything's placement will be included, but that might take nearly a year to complete.
