There was a piece I had designed on Rhino during my first year of B.Tech which has seemed to have found a place in my current work so I have taken steps in printing it last week. The picture in on the bottom left is a CAD/CAM drawing of the ring view of the two part piece.
After the print I found that the desired effects which I wanted were not possible and will therefore mean that I will need to reprint the top piece and adjust the design a little.
