The crew over at ETradeSupply has long be selling BlackBerry 10 and older parts for repair and replacement. They usually are one of the first to get the replacement parts in stock and show them off. Now they have put together the basic steps needed to disassemble the BlackBerry Z10 to repair common items like a cracked screen, busted speaker, or broken charging port. They have a full take apart tutorial for the Z10 as you can see below but I recommend checking out their new step by step tutorial of how to replace the most common parts at this link.
