HP Series-80 computers - PRM-85 board case? ... maybe!

    Marlin, why not try to find a hackerspace in your area, they usually 
have 3D printers and willing to help.

I own PRM-85 boards for my HP-85 and 86 machines. While they are very useful 
extension modules for these computers, they lack a proper case. I hate to 
destroy a working interface or memory module just for the case.
I read in this list that there are more people interested in such a case.

So I designed a replica case for 3D printing, but did not yet try it out.

I do not own a 3D printer and the commercial services calculate between $20 
to $100 for one shell (upper/lower).
This is a bit expensive for some trials, as I expect that the 3D design 
would need some iterative refinement to obtain a "perfect" case.

So: if someone owning a 3D printer and a PRM-85 board is interested in 
helping me to refine the design by making a test print I could supply the 
STL files for upper and lower shells. As a "thank-you" I would expect 
feedback to improve the design.
