Articulated Codsworth Stand

This is one of my first Tinkercad projects. It is a stand for the Articulated Codsworth print http://www.thingiverse.com/thing:1202520 . Because of my small print bed size, I had to build this for a scaled (.839) version of the print. Therefore, this should be scaled to 1.161 to fit the full size print. It still doesn't lock on to Codsworth as well as I would like, but like I said I'm new at this. If anyone would like to improve upon the design, the tinkercad URL is https://www.tinkercad.com/thi
