I have a 3d model that could be printed for that screen we have. I can send it to you if you want it. I got it from another site, then one of our mechanical engineers modified it a bit because there was some scaling problem. He was going to have it printed at a public library but they wouldn't because they said it would take too long (they have size and time limits). it's not really a wall mount, more of a case that sits in a stand.
I'm with you, I spent a little time looking into 3d modelling. The ME at work offered to sit down with me and show me the ropes, I'm going to take him up on it pretty soon. A few of us have been talking about going in on a 3d printer, we haven't pulled the trigger yet, but I think we might once we figure out what we want.
