Hollow ball that can open

in Product Design held by vim33
Contest Ended, Winner(s) have been selected.
Description:
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.
Wants:
I would like to see the object in the following colors: baby blue, pink, light green, white
Software:
  1. AutoCAD (latest)
Additional Information
I will need the project in 2 files: AutoCad (.dwg) and STL

The Upper Portion Contains a lock. After entering into the bottom part a simple clockwise turn will attach them . To open the upper part a simple anti clockwise turn will do that.

Dear vim.

top and bottom spliting is equal or difference. because your input sketch (top view) showing two circle its meaning top and bottom splitting is not equal size. please clarify

Design123, as long as the format is in dwg or stl it should be fine.

As for "Also should I provide lock which will be tight fit in same model/dwg" - I don't know what you are asking.

Dear sir, Can I submit dwg and stl format which is created and converted by Unigraphics or Cimatron . Also should I provide lock which will be tight fit in same model/dwg?? If unigraphics/Cimatron allowed, should I sent 3d model file?

How do the top and bottom attach to each other? Should they be threaded, glued or joined with snap hook & groove? Or else?

If you can imagine the plastic eggs used for kid's easter egg hunts. It would be something similar to that where the top and bottom halves of the egg snap together. Although the difference would be this project's hollow ball would have a strong, tight fit between the top and bottom pieces.

Can i upload Pro E, IGES<STL or STEP format for 3D prototyping.Otherwise are you looking for only autocad
format

Sprocket Assembly
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, Frank
