I am amazed that I successfully made this.

The store had this 128 MB flash drive for 15 bucks. It was cheap enough 
and large enough to be worth it... so I tried to make one.

At first, I wanted to use a single brick. I changed my mind after I 
figured out that it would be really hard and would leave a empty bottom.

I used dremel tool to crave parts out, and I wasn't exactly expert 
on this, so I made many mistakes and gouged some of the outside walls. 
You can see the gaps in one of pictures.

Fitting it were pretty tough, since I had to make walls thinner too! 
You can see yellow and one of blue plates has about half wall thickness 
left.

The USB drive happened to have this metal part that was bit higher than 
all other parts. That proved to be a nightmare to fix. The top plate has
that craved out part (see ZParts, part A near the right end). I keep 
having to take more and more, hoping not to poke though the other end!
In the end, it worked, and it was convient at the end... read on!

After finally fitting all parts together, after removing and testing and 
removing some more, etc... I had this problem.. The plates will hold 
together, barely. I removed so much. I decided to use super glue to put 
them together.

The USB part could slide out and in a little so I had to figure how to 
make it stay at place. As it turned out, I fitted that metal part so
closely that it was touching ABS plastic! So I used that spot to super 
glue the USB drive into A part.

Rest was pretty hard, since I had to apply glue into pretty thin walls and 
put them together and aligned. 

It looked good, so I tested the drive. What? I can read and can't write?
Apperently, when I was getting it together, I acciently hit the read-only 
switch. I had to pull it apart and hit that switch. It wasn't easy since 
It was partially cured by then. Well it works now.

Only thing to do is figure how to polish the sides so it will look good 
after the super glue damage.
