Draw out the front blaster part. The thing that looks like two half circles on a rectangle. Make it about four inches tall. Trace three of those after you have cut the first. Cut two lenghts of cardboard about 8 inches long. Cut a trigger type thing (see picture) also four inches long.
Step 2: Glue
Glue the blaster and two lenghts of card board together. And trigger guard on the opposite end. Use two cardboard lengths to seperate each blaster part from each other. For strength, you can use more lengths of cardboard on the side like in the picture.
Step 3: Finish!
Color if you choose, but other than that, your done!! Thanks and feel free to send suggestions for other projects.
