Ok folks here are the links, I finally got everything set up. If you order 1 of each of the 3 the total will be $42, but all 3 as a set will cost you $35. If you order individually you can mix and match the colors, but order all 3 you can only order them in one color.
As all things in a pinball machine if these are hit by an airball they can break, but so do all things that can be hit with an airball. These are solid resin, not PLA printed with a honeycomb structure that can crumble. These are just as solid as something that is a cast production piece. There are fine details on these and can snap if squeezed too hard or handled irresponsibly. But once installed they should be just as permanent as any other addition to your machine.
These were modeled by me and have a lot of detail for such a small piece. Just be gentle while installing. You can secure these with double sided tape, rubber cement, I would NOT suggest super glue as these might need to be removed later for moving, cleaning, or general service. They stay on just fine and should not come off unless you are a Tilt junkie and turn the whole machine 60-90 degrees.
These can be ordered in pink or green or several other colors in case they make sense on another machine. I would say something like Dracula or Tales from the Crypt where blood would be fun.
