The "heartflex" style clips on the door trim panels (white in all but the earliest cars) are one time use, so they should be replaced any time the door trim panels are removed. The Telsa part number is 1025401-00-A.
When I was still working for Tesla, I looked up the engineering drawing for this part, trying to see if it was something that could be easily found aftermarket. They're made by a large industrial products manufacturer, but I couldn't find anyone selling that particular model number online, so it's probably custom-made to Tesla's specification. It's quite possible that the thickness of the aluminum panels vs. steel is the reason.
