Ice beam from metroid prime

This is a real life model of the ice beam upgrade from the game metroid prime. The box pieces are designed to hold one arduino uno battery pack and one 3 x AAA Battery Holder with On/Off Switch and 2-Pin JST.
The model itself can be built using just the model pieces with glue to hold them together, the box is not necessary unless you intend to use electronics in your model.
