Custom Dock for BlackBerry?

I've had my 9900 for quite some time now, but I don't want to shell out a lot of money to buy a charging pod/dock. Could someone show me ways to make custom DIY docks out of maybe cardboard or plastic cards that would look great and still be able to do the job? maybe even have an input for the USB cable charger? (I know I'm getting a lil greedy here :D) If someone could share some links or a video specifically for the 9900? Thanks in advance :D *can't wait to get my craft mode on*
