I recently created some custom inserts for my Williams Getaway, and realized there may be other pins out there that some of these would apply to (just about any racing/car theme). Please note that these are designed for the coin reject buttons used by Williams but may be the same format as other manufactures (I know that Stern is different). Dimensions on these are .625" (5/8) by 1.1875" (1 3/16)". As with all my other designs, I'm putting these on my Getaway site for free download: http://www.thezumwaltfamily.com/getawaypinball

For my own I printed on high quality Epson paper (not photo stock since paper needs to be thin). This paper gives a nice crisp image and very even non-splotchy light diffusion. but if you can't make your own for some reason and want to have them, then I would be willing to print you a sheet with multiple copies of each insert for $3 included postage (sorry, I know its just paper, but I have the expense of the envelope, postage, and a little time).

And here is an example of what they look like on my Getaway using red frosted domed LEDs:

Well, this is the only pin I currently own so hadn't planned on it. I could be persuaded however if enough demand for specific pins. Might need some help for ideas if other pin specific.

FYI, a friend pointed me to this thread which got me started: https://pinside.com/pinball/forum/topic/free-coin-reject-inserts-for-modern-sterns-10-games

Very cool, thanks for posting the link.
