Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Materials and Tools

  • Two small shotgun shells
  • One USB
  • Foam/Tissue/Sponge
  • Paper
  • Red pen
  • Electrical Tape

  • Vice/Clamp
  • Craft Knife
  • File or Dremel

Step 2: Stripping the USB

We need our USB to be as small as possible so it can fit in the two small shotgun shells, this means we need to remove the outer casing.

Using your craft knife pry at the edges of the case forcing it apart.
(The cases are generally pretty to take off)

You can now throw away any of the plastic casing
(Better yet recycle it !)

Step 3: Preparing the Usb

Now you have removed the protective casing it would be a good idea to cover up the bare circuit board with a bit of electrical tape.

The tape will protect the circuit from short circuiting or getting damp.
(Still best not to go swimming with your USB :P )

Step 4: Filing the Shells

Because of the small "lip" at tho bottom of the shell the two cases wont stand very close together.

To make them stand snug together we have to loose a bin of that "lip"

Clamp the shell in your vice/clamp and then use your dremel or hand file to flatten one side.
Repeat this process for both shells and check they fit together.

Step 5: Cutting the Slots

Now we need to cut the slots in the sides of the shells so our USB can fit in.

First mark the shell with a pen to show how much to cut, this will prevent you from cutting too much and loosing the aesthetics of the shell.

Now you have marked the shell carefully cut a slot into the side with your craft knife, do this to both the shells.

Step 6: Assembling the Case

Now we have the slots cut into our shells we can finish up the project

First put the USB into the slots, then for extra protection get some sponge/foam and your craft knife
Cut strips off and stuff them into the space surrounding the usb.

Once all the space is filled get some paper and cut two small disks, then trim them and glue to the tops of the shells. Once glued use a pen to colour them in so they blend in with the rest of the shell.

If you get lost then just look at the pictures or leave a message !

Step 7: Finished !

Congrats you finished
Thanks for reading !!
and if you made it you can go show off your awesome mod to your friends ~~and gun totin' uncles~~

    I'm assuming those are 20 gauge shells right? I think it would be even better if you could fit a USB into a single 12 gauge shell.

    they are 12 guage shells standard red color and pretty ordinary.... just like the ones i use

    Those are .410 shells, they are .410" in diameter, a 12 ga. shotgun shell is .75" in diameter. You can see these are .410 shells when you compare the male USB 2.0 connection to the diameter of the plastic shell, male USB 2.0 connectors are .5" in width. You state that "they are 12 guage shells standard red color and pretty ordinary.... just like the ones i use", the color does NOT indicate the size of the shell ( this picture shows just that ) and if you truly do use a firearm of any kind, I suggest you go to a hunter's education course.

    nice idea i would recommend using a 20 gauge or a 12 gauge shell instead of a .410.

    the red ones used here are standard 12 gauge, so yes i agree 20 gauge are slightly smaller so it really depends on the size of the flash drive


    Reply 9 years ago on Introduction

    Judging from the size of the USB plug end, these are NOT 12 Gauge shells, definitely .410 shells. If 12 Gauge shells were used in this project, only ONE shell would be needed because a 12 Gauge shell is plenty large enough to hold a USB flash drive.

    Great instructable!

    When your USB is plugged in, it looks like your computer has been shot by two bullets!

    hey plasmana, i guess you have never been around guns or even shot a gun or you are just a little kid, because the shell (or casing in a rifle) does not leave the gun.. only the bullet or pellets or BBs do.

    A mere technicality on my part, yes the shell does leave the gun *when ejected after being shot* but what I was trying to say is that the shell does not go flying out the barrel when it is shot. That is what I meant by "does not leave the gun, just the bullet, pellet, etc.."

    MISUNDERSTAND! The shell doesn't come out the end of the barrel, it is ejected out of the chamber to the side


    Reply 10 years ago on Introduction

    Yeah, thanks for pointing that out, I know the case does not got with the bullets, lol. I'm just saying it "looks" like the computer has be shot. :-)
