WARNING: hollowing out cork is dangerous is knife cuts through cork. Some hot glue guns may be too hot and could damage your USB memory. I'm not responsible for any damages (to you or your USB).
This is for the Pocket Sized Comp(It's my first instructable ever).
Step 1: Find Materials
Cork (the larger the better [Champagne cork even better])
USB (Buy only insides or open yourself)
Hot glue gun
Pocket Knife/Stanley Knife (preferably small blade)
Permanent marker or felt tip pen
Step 2: Cut Open Cork
Mark on USB with marker where actual USB will enter USB port.
Cut straight down the line into 2 parts.
Step 3: Hollow Out Cork
Then, with knife, cut around the colored in box.
Cut as deep as you can.
It doesnt matter if the knife goes out the other side but try to avoid that happening.
Step 4: Inserting USB
If it doesn't, then keep hollowing out the cork to make a bigger hole.
If it does then go onto next step.
Step 5: Glue in Place
If it does then glue on both sides of USB and quickly insert into cork.
Put some more glue in on the sides and squeeze cork slightly to make sure all glue sticks onto cork.
Step 6: Finishing Up
Find some large pieces out of the pile of leftovers.
Dab some glue where your going to fill and fit the pieces into the hole.
