Prototype case

Hi.
Not sure where to search, so hope you can help me.
I finish my project and need a custom case for my device. A good quality 3D printer will be to expensive.
I will like to have a good finished case, similar to the imac mouse, that is a bright plastic (like this).
Probably for a prototype a low quality case will be ok.
Any idea of were I can make a custom case?

Thanks

Javier

A big block of plastic (or wood) and a knife?
Nothing wrong with using your hands

For just one, this is great, but if someone wants to mass produce it, by hand wouldn't be very ideal...

Shapeways.com is the go-to place for high quality printed parts.
