04 May 2015: 2nd revision, progress so far

First revision was aesthetically not adequate: this required a redesign from scratch which has taken approximately ten weeks to get to the point where parts could be printed off for testing and demo purposes. This time, the bulk of the parts had to be designed together before endeavouring to print any of them out, as well as then design the method by which the parts fit together. This significantly slowed down progress but ensured that the end result was much more aesthetically pleasing.
