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

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.

Oyster Cage
I need some oyster pots. The wire mesh will be 1/2" and the sides and center support will be made out of plywood. The mesh will be plastic coated steel from Riverdale Mills (1/2" center to center). Cage will be a cylinder with a 12" radius and a length of 4 feet. There will be a 3/4" rod passing through the center. Unlike other cages, one end will open for loading and unloading the oysters. See theoysterguy.com faq pdf for an idea of what I am looking for. Also see attached picture. I have come up with one idea for closing the ends, but any other ideas will be appreciated. The parts will be cut out of 1/4" plywood and cut out on a cnc machine (shopbot). Parts will then be coated in epoxy to make them waterproof. I want ease of assembly. Notches to align wire mesh. Longitudal arms should notch into center piece and have tabs to align outer ends. There should be hole in the sides to allow for waterflow and leverage when closing and opening one end.
