Check out the first entirely 3D-printed proton pack

Get ready to weaken ghosts by firing a stream of protons from this 3D-printed pack. 

Our friend Thomas Lemieux, more commonly known as ironmanofmaine, has returned with a slick new project. Before beginning the latest iteration of his incredibly impressive (and popular) Iron Man suit, the Maker has created what is surely the world’s first entirely 3D-printed proton pack.


The proton pack is a fictional energy weapon used for weakening ghosts and aiding in capturing them within the Ghostbusters universe. For those unfamiliar with the 1980s flick, it has a hand-held wand (particle thrower) connected to a backpack-sized particle accelerator that is capable of firing a stream of protons that polarizes the negatively charged energy of a ghost, allowing it to be held in the stream.

Stemming from his World Maker Faire 2014 costume, which indeed generated quite a bit of attention, Lemieux has logged his build here. Meanwhile, the photos can also be seen below!
