I originally saw this idea of a Shuriken USB on the internet and decided to make one of my own. I thought of a simple and quick way to replicate the idea using foam cored poster board. So by following these simple steps you too can make your own and have a cool looking USB.

Please vote for this instructable and feel free to ask any questions.

Step 1: Materials

These are all you will need to make your own Shuriken USB:
a ruler
a pen
a needle/pin
a x-acto knife
a piece of paper
Foam core poster board
a glue stick
a hot glue gun
Paints (and any extra materials to colour or design your USB)
a USB

Step 2: Design

This step is really up to you. Just draw the outline of the design of your Shuriken onto a piece of paper. Mine is a simple four pointed star.

NOTE: your design must accommodate for the size of the USB you are using

Step 3: Transferring the Design

Now you will need to transfer your design onto the foam core poster board. Just place your design on the paper over the board and use the needle to plot points onto the board. Then just join these points together by drawing a line on the poster board.

NOTE: do this step twice as your Shuriken will be two cut outs stuck together to accommodate the thickness of the USB

Step 4: Cutting Out

Now its time to cut out the Shuriken. Use an x-acto knife and cut along your lines carefully. Remember to cut out two pieces.

NOTE: take time to cut your lines to keep them straight. Make sure your lines are cut properly to avoid tearing the poster board.

Step 5: Bevel the Edges

Now its time to make your Shuriken look sharp.
Mark out a line on the cut out stars about 5mm (1/4 inch) from the edge. Score this line just cutting through the first layer of paper (this will make it easier to cut out the bevels). Take your x-acto knife and at a 45 degree angle cut around your design. You should now have a 45 degree bevel around the outside. (do this for both peices but invert the bevel so they come together to form a sharp point)

NOTE: take time to make these cuts as to not tear the foam or paper. And again be safe with knives.

Step 6: Make the Lid

Now just cut off one point of the star, this will be the lid. (do this for both pieces)

Step 7: Make Room for the USB

Place the usb over the inside of the pieces and mark out its shape. Cut out this shape through the first layer and foam but leave th paper on the outside in tact. do this for the lid asweel but only the for the top part of the USB (the lid). Now remove the cut out section to leave a space where the USB will fit when the pieces are placed together. Glue the two pieces together and the two sides of the lid too.

NOTE: don't cut through outer layer of paper, this will ruin the outside

Step 8: Finishing

Nearly done. Now this step is up to you as it can be your design, paint it or cover it anyway you desire. Then glue in your USB and thats it!

I decided to paint my Shuriken black with acrylic paint  to seal the foam and then coated in Spray Paint and cut notches to give a broken and battered feel. I then covered the sides in aluminium foil and re-cut the noches to make them visible.

This can be your design so do what you want with it, make it creative!
<p>this looks very cool. i saw the same thing you saw on amazon and i really wanted one, but it would be a lot of fun to just make one for myself.</p>
<p>Hi great design! How strong is it? I feel like if I make one its going to break :/ Does the PVA strengthen it much?</p>
Hey, I think you should modify it so that each &quot;blade&quot; is a usb drive (4 total) <br />Although i don't think they will all fit with the size that you have but, there are smaller ones out there
Yours is the coolest looking USB to make it to the finalists, in my opinion. Nice job, and congrats!
thanks mate, i liked yours too<br>
Sure, and glad you liked it!
that looks awsome, makes a simple work transference into somthing epic
thanks mate<br>
id you use hot glue gun to glue in the usb, or did you use epoxy or super glue? im almost done, just need this one simle question to be answered.
I would reecomend using hot glue like i did, it fills in the spaces around the USB a lot better and the overall strength of the bond isnt too important<br><br>
the acrylic is important. Without it, the foam 'recedes' and you will need to start over.
yep, it would ruin everything
I didn't read all the instructions while i was working on this, so i just went ahead and spray painted it. Whoops... learning new things every day
:(
do you think a USB cap is necessary, or will the foam core board be enough?
it will work either way, you can use the cap to make the top stay on better but it is not needed if you dont want to<br>
did you take the case off the usb before you attached the shariken design to it?
no you dont need to, you just cut to the size of the case. Its up to you.
how thick is the poster board you used
it is 5mm thick poster board<br>
this is awesome. i voted for you in both contest enties.
thanks mate
what kind of paint did u use on the front &amp; back of the shuriken?
i first sealed it with just a pva glue, then coated it in a couple light coats of spray paint, you could also clear coat it to make it shiny<br><br>
hey coul you do this with just the insides of the usb? oFTo
yeah, just cut out a little less to make the circuit board fit snug to avoid damage<br><br>
Cool beans!
thanks mate, please vote<br>
Thats just awesum. My sis would love it... nin-star headphone holder anyone?
That would be amazing. Nin-Star Headphone holder. Yeah!
thank you very much and dont forget to vote<br>
Awesome ible! Ima full ninja fan anyway. But i don't think i'd throw this one.<br>Great Work!!
The amount you Rule is beyond words good Sir :D <br> <br>I wnated to use Fimo, but your design is better <br> <br>Thank you for sharing :)
