My son purchased his own 3D printer and has enjoyed making all sorts of things. That's a good thought that he might make templates with it. His has a 10 inch pad so nothing over 10 inches could be made. It might be hard enough, you could make it as thick as you like, but it's not see thru. It could make the ones that you go on the inside of a hole in the plastic. I may have to give that a try. Thanks for the idea.
