Sprocket Assembly

in Product Design held by Frank
Contest Ended, Winner(s) have been selected.
I have a design that in appearance is similar to a sprocket and hollow shaft. There is a need for a 3D model that can be used for rapid prototyping/molding. The final design should be in Autocad 3D and as shown in the Sketch referred to as Fig. 9.
Attached are two 2D Autocad drawings of the “Support” and a “Tube”.
Also attached are two scanned images Fig 1, Fig 2 and Fig 3 of the changes with instructions.
Originally the Tube and Support were designed as two separate parts to be assembled together, but the new design requires that they are to be made as one “Assembly” as shown in Fig. 3.
The following changes have to be made to the Tube FIG 1:
The Tube has to be reduced to 2 inch long.
The top portion of the tube has to be deleted.
The Tube Outer Diameter has to be increased to 7/8 inch and the wall is 1/8 inch.
The Tube is now placed on the support aligning the Slit
This makes the Tube and Support one piece called the “Assembly”

For additional information see Fig 2 and Fig 3.
The 3D drawing will be used for Rapid Prototyping.
1. I would need a 3D drawing in Autocad, and possibly also in one of the following formats IGES (.igs), and/or SolidWorks (.sldprt) and/or Stl that is generally used for Rapid Prototyping.
2. I will also need the 2D drawing of the Assembly in Autocad.
This design is not to be distributed or used by anyone else without prior permission from me. All items sent to you must be destroyed or returned to me.
Thank you,

Hollow ball that can open
I need a plastic prototype design in 3D. This object is a hollow ball (20mm in diameter, 1mm in thickness). The ball is composed of 2 parts (top and bottom piece). The top piece will slide into the bottom piece. On the top of the ball are small air vents (0.7mm) that form the shape of a circle. The bottom of the ball will have an opening (4mm diameter). There is a small arch inside the ball that sits at the base. The arch will extend from one end of the opening to the other. The arch will will be 1 mm in thickness. I have attached images I created with paint.
Plastics Engineer Needed
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.
