Micro USB right angle male connectors:
And for wires and the sleeve, there's many things you can search on ebay. I used what I had left over after doing a DIYmod (iPod 5G mod) which was a 30awg solid core pure silver cable (I can't find the seller anymore). Ofcourse it's USB so it doesn't have to be silver or single core (you can use copper and stranded wire too), I just used it because it was the most thin cable I had and easy to work with. The micro USB connector's solder points are small, so it's easier to use thin cables.
I recommend 30awg to 26awg, anything lower number or thicker may still fit but maybe you can't use sleeves beyond a certain thickness. In my case I just used thin cables and covered with a 3mm red sleeve I also bought on ebay, just to give it a tidy look.
You don't need to buy from ebay if you can find connectors, wires and sleeves locally.
