I'm playing around with the idea of creating a window decal for the Monger plate on Iron man. The sticker would stick to the inside of the window so the ball would never wear it down and there would be a spot on the decal that would be transparent (the window) so you could still see the monger. Here is a sample of what I envision. The print will be roughly 100% opaque with a cut out for the window. Transparency were not recommended for the yellow.
These will be $12,50 shipped worldwide. An official FS thread will be started once I iron out the details.
Revised with bigger and alt window with word danger added.
Revised with 3 part option. You can either keep the "spinner raise monger instructions" or add the second piece of decal with the warnings and replace it.
