Calculator case
As I live in the Philippines, I have good access to manufacturers of plastic cases. My question is this:

If I make replacement hp cases for the 29, 34, and 41, with no HP label or markings, would I be violating any patents as they are quite old designs? If the answer is no, would it upset HP?

I will sell them at cost plus shipping - so I'm not getting rich off of others work. I just plan to make them available to collectors. I also plan to stuff them with new guts, again at cost. The software is free and open source.

If this will step on anyones toes, I will not do it. Any thoughts are much appreciated. Thank you.
