This is a replica of a portal gun. It is made to print in the correct colours and has a cavity in the main body to apply LEDs on the inside to light up.
 

The claws on the front can move with a single point of articulation.
 

The model has been optimised to print with as little support material as possible. The STL files have been optimised to print in the best orientation.

HOW TO BUILD
There is a great Step by step blog from Jayko Torr that shows his process of making the portal gun and adding in electronics too.
