How to Make a 3D Cardboard Gun

by Lindsay Howell

Using cardboard, you are able to build almost any prop that you may need. Building a gun using cardboard is a good idea because a cardboard gun looks enough like a real gun to use as a prop, but not enough like a real gun to get you into trouble. To build your cardboard gun, determine what kind of gun you want to make. Do not start working on the cardboard until you have figured out what kind of gun design you want to build.

Items you will need

  • Utility knife
  • Acrylic paint
  • Glue
Step 1

Draw a gun design on the cardboard. For instance, if you are making the Beretta M9 9mm pistol, draw the barrel so that it is 8.5 inches long and the handle is about two-thirds of that size. Draw the height so that it is 5.5 inches tall.

Step 2

Draw the same design as in step 1 on another piece of cardboard.

Step 3

Cut out the designs using a box-cutting knife.

Step 4

Cut out a long strip of cardboard to act as the width. For the Beretta M9 9mm pistol, cut the width so that it is 1.5 inches to match the actual width.

Step 5

Paint all of the strips the same color. Most guns are silver or black, but feel free to paint the design whatever color you want. If you are painting the cardboard Beretta pistol according to its actual color, paint it black.

Step 6

Lay the strip of cardboard between the two gun designs. If there is any leftover strip, cut it off.

Step 7

Glue the edges of the strip to the gun designs. Glue the two ends of the strip together.

Tips & Warnings

  • If you are using the cardboard gun as part of a prop for a costume, paint the tip orange or attach an orange tip to the end so that people do not thinking you are carrying a real gun.
