I can model to a certain, very limited extent, but mainly just modifying meshes. So, I'd be really grateful if someone could make a simple model and UV map based on this picture I whipped up in photoshop:

The black parts are medium sized indented (rigid, not rounded) holes, there should be 4 of them equally spaced around the sphere in the pattern shown. As for the texture, don't bother. you can just color code stuff like the inside walls of the hole, the base of the hole, and the body in distinct colors and I can texture them. The model should be about the same size as the original portal sphere.

If anyone is interested, thanks in advance
If someone makes it for me they'll be credited in my mod

EDIT: Forgot to say this was for portal 1.
