Is there an interest in 3d printed custom enclosures?

Riva:
That's a nice idea but what continent are you based on?

I am based in Victoria, Australia.

codlink:
There are generic enclosures for the different Arduinos, but you could offer custom enclosures and design. If you were fast and did it at a reasonable price, you could make some money.

Yes, I have seen many generic enclosures. My intent was to make a case for my Arduino Fio and components as there are no enclosures which accommodate for my needs.
As I stated previously I wanted to keep these reasonably priced and as for the speed in which these can be produced is dependent on the design and also if the customer supplies a cad file or not. I could also offer some generic designs.

This is just a concept so further ideas may be implemented.

Thanks
