Aside from just being cool this tin will allow you to carry your pocket camera around in your pocket without having to worry too much about keys or loose change damaging it. I don't know how many friends I have that broke the LCD screens on their pocket cams from just tossing them in their pockets.
Materials & Tools:
50g Altoids Tin (flavour is up to you)
Foam or soft thin fabrick
Dremel type cutting tool
Needle Nose Pliers
File to remove sharp edges
Step 1: Cleaning the tin
Mint dust while tasty isn't the best thing for camera lenses etc. Run the tin under a tap and then dry thoroughly with paper towel. If you have a can of compressed air it wouldn't hurt to give it a quick blast just to make sure its all gone.
Step 2: Test fit to see what material to remove
Place one end of the camera into the tin and on the other side mark the area that is interfering. Now is also a good time to line up where the camera strap is so you can cut a slit for it as well.
