Well, I hate wire strippers! It's a very cheap and (I have to admit) pretty flexible, but when it comes to anchor the wires in limited and crowded spaces... not to mention the risk of chopping the wires when you want to remove one (and, yes, you have to cut it even if you want to take out one wire only!) You will get quickly in love with this clam thingy. It is designed for 6 mm rods, 'cause that I needed :) Managing the wires Simply attach it on the rods of your RepRap by pushing the opened end against the bar until it locks. Either push the wires through the large loop, or push them through the tight opening of the loop. If you have a clear idea of which wires should go through one clam, I'd recommend you should insert them before attaching the clam to the frame, especially in crowded places.
