Functional USB Flash Drive Rubiks Cube

Step 3 Modify the cube pieces

Use the edge piece as the top and corner piece as the bottom part and get rid of the inside as shown in the picture. Make sure to leave two pins (“circled” in blue) in the middle of the edge piece, which will later be used as a guard rail (don't worry about the height yet). In order to drill the hole in the middle measure the stick and mark the shape. It doesn't have to be to neat, because you can later fix it with the modelling clay.
 

EDIT: Some people asked me about this step, I hope that the second picture is better (yeah I know it looks pretty gross ;-)). As you can see I did not drill the whole inside of the edge piece away (to make sure that the drive slides up in the right way). The grey stuff is Apoxie Sculpt I used it to try to get a better result, but it is not necessary.
