Replacement bottom cap for stick up camera?

Hey community. My wife and I just moved into a new home and acquired a few stick up cameras that were already on the property - we also purchased a few new ones. One of the existing stick up cameras (outside, latest version, battery) is missing the bottom cap (battery cover cap). I've done a ton of searching and cannot find anything for a replacement part. Am I alone in this quest? Perhaps someone has made these via 3D print? Any advice is appreciated. Thanks!
