This is a custom 3D printed mount for pinball life product SKU: PBL-100-0062-00
"External Volume Controller for Stern Machines"

This is for earlier machines that do NOT have a square hole in the front of the cabinet, but that can be used with the pinball life volume control.

This is designed to match the original steel plate that is on the door that is used for bill acceptors.

if you like for an extra $2 I can prime the plate and spray paint it with hammered gloss black paint for a finish that is closer to the original coin door,
(note it's not a perfect match by any means, but a little closer than the flat black of the plastic)

otherwise the plate is the normal flat black 3d printed finish (though it is very smooth) and you can apply your own paint or decals or whatever to fit your cabinet as you'd like.
