I made this in about 20 minutes, it was pretty easy to do.
I am sorry if this is the same as about 5 other instructables, I did not even know they existed.
Step 1: Materials and Tools
A Hot Wheels car
An old flash drive (with a broken case if possible)
A drill and bits
A Dremel with a small cutting wheel
A Phillips screwdriver
Step 2: Opening the flash drive
One of my flash drives was.
One wasn't, so i had to cut the pieces holding it together.
This step can vary depending upon your flash drive.
Make sure to keep the cap.
Step 3: Drilling out rivets
This is how mine were put together, but some may use screws, in which case, just unscrew them and take it apart.
For rivets, find a drill bit that is quite a bit bigger than the hole in the end of it, and drill a hole in the rivet.
Some cars have two, some have one.
Step 4: Prying apart the body
Note: Do not try to go in between the wheel and the bottom, this will wreck the axle.
When this is done, take out the seats. They are not glued in.
Step 5: Cutting the Rivets
Step 6: Cutting the body
File the hole smooth.
I got lucky, and my cars had holes in them so I could easily remove the peice that I cut. If you aren't so lucky, you can finish the cut with your Dremel.
Step 7: Glue it together
Now add the flash drive and glue it to the bottom of the car, and glue the bottom to the top.
