Pictured here are some sample renderings of the final concept design. The virtual parts shown in the renderings were converted into technical drawings, which were then used in the manufacture of the actual parts used in final machine assembly. In other words, this is the virtual rendition of the theoretical final state of the actual straw cutting device.
This is the blade carriage subassembly rendering, complete with linear shafts and bearings, blade, and mounting hardware.
This rendering is of the vacuum attachment that was rapid prototyped using fused deposition modeling technology.
If the renderings shown above don't satisfy all manners of curiosity, the part files are available through the link below, and can be viewed and manipulated with SolidWorks 2010 (or possibly later versions of SolidWorks, as well)
