My only experience with STL generation is with OpenSCAD; creating a model for the I-195 would be difficult because the shapes are so odd. On the other hand, making the model for a 7x9 matrix for NE-2 bulbs would be pretty simple and could be done in a few minutes.
I'm going to wait until I get my displays and have a chance to light them up to see if like them enough to make copies of them. Here's a picture from the seller with all segments lit. From that you could produce a model for 3D printing. This display is pretty large: 65x95mm so each segment is roughly 1/4" thick (about the diameter of a neon bulb....). If I do decide to go ahead, I'll be making PCB's for the 7x9 dot-matrix, and this I-195. I predict the I-195 will use 26 to 28 bulbs.
