Looking for a ATX case side panel door

[ThinkPad560X]

I am looking for a metal side panel door. The other side panel is 15-5/8 tall by 17-1/2 long and should be the same minus the vent holes.
Looking for the vented side that looks like this one. https://www.bhphotovideo.com/c/product/ ... assis.html

I think there was a few custom atx cases that used these side panels.
It looks like a Cooler Master Elite 331 uses the same door.
