Thanks for introducing me the Makerbot store. I wished Makerbot would give you some advertisement token and the same is Rigol. Wow, Maker Bot gave you one complimentary to demonstrate for us, neat. Was not for the EEVblog, then I would not have taken interest in these items. The Maker Bot (3D printer) is better than the Growbot (robot cart) from Parallax, that I tried to help a friend assembled for her San Jose State robotics art class. Wow, this a 3-D printer. I would like one to make parts for electronics like light switch knobs and maybe the plastic cover parts.
