Coin Door Button Supports
Purchased a blank coin door from VirtuaPin and 3D printed these little supports for my coin door buttons. There is a right and a left, one of them has an extra hole to route the wires. They bolt right on with existing hardware and use the existing light, soldered the wires on. Then mapped them to the insert coin button feature. I hooked mine in parallel so both do the same thing but, sky is the limit, vol up and vol down would be a good idea too.
Used these buttons from Amazon
