Custom Portal core

thingiverse

The movable core from Portal allows you to look around and experiment freely. Designing its configuration is entirely up to you. To bring your creation to life, print out four Core handles, two inside rails, two outside rails, and two rail décor pieces. I've also integrated the Space Core eye with complete accuracy. For a smoother eye movement experience, try lowering the rotation speed by reducing the file depth of the inside rail, making the spin cleaner.
