To model the long hockey bottle spout for use with a standard water bottle. Also, gatorade bottles. Design cad file so prototypes can be made

I am working out a proof of concept for a marine habitat and need an expert who understand techniques of pvc/vinyl or other plastic joinery, using specific glues and (initially) existing extruded shapes. I will provide sketches and my ideas. The plastics engineer will provide feedback and (later on) CAD.

We have created a game changing new version of the guitar capo. Our patent pending design eliminates the short comings of all modern capo designs. We have created what we call a "reverse nut" that keeps strings from binding in the capo. When the strings are bent up to pitch, they will return to original pitch without getting stuck in the capo. What we need: 3D CAD product rendering for prototyping. Capo Definition: "Musicians commonly use a capo to raise the pitch of a fretted instrument so they can play in a different key using the same fingerings as playing open (i.e., without a capo). In effect, a capo uses a fret of an instrument to create a new nut at a higher note than the instrument's actual nut. There are capo designs, but most commercial capos consist of a rubber-covered bar that clamps to the instrument's neck in some way to hold down the strings. Capos come in different sizes and shapes for different instruments and fretboard curvatures. The most relevant mechanical factors that vary by type of capo are ease of use, size, degree of interference with the player's hands, and ability to hold down strings uniformly without affecting tuning. Musicians use capos on many stringed instruments: guitars, mandolins, mandolas, banjos, bouzoukis—virtually any instrument that has strings suspended over a fretted fingerboard. Capos exist for square-necked resonator guitars, some of which do not contact the neck, but clamp above and below the strings." Wikipedia

Commuters on buses and trains don't have cup holders, and so they are left with the balancing act of holding their travel mug in one hand, while trying read the paper or work on their laptops with their other hand. This sucks, causes spills, and is super uncomfortable. Commuters need something that's compact and foldable that can then open and attach comfortably to their knee (or another body part?) that will securely hold travel mugs of different sizes.
