I know that I'm posting a lot, probably too much. But I'm sure the volume will drop off eventually. This piece is pretty esoteric, all things considered. You have to have something you need to mount to make use of it. I want to play with pulleys and block and tackle, so this will help me do that. This is the whole point of these machines. You can think of something, design it and turn it into reality. Sure a lot of things like woodworking and metalworking give you similar powers, but those things are difficult and time consuming. Once you get the hang of your Makerbot, designing and printing stuff becomes much faster than any other type of fabricating process. This is why I love it so!
