Thumbs up Need Guidance for Making my own OTG Y cable for Droid Razr xt912

Hey everone, I did some research and found that OTG cannot work on this device unless you provide a separate power to your USB device that you want to connect with Droid. So I want to make my own OTG Y cable please give me some good ideas to make it look neat n clean and if you have made one please post its picture, thanks
