This is likely too easy, but I can at least upload again. Thanks to KyleK

Object is a roughly 2.5" X 3" oval.

A quick disconnection adapter for a tripod.

Yes! Easy, that.

While you are up, plotalot, I will scour my home for better stuff.

I know right, I was waiting for @gynojunkie to post a picture of one of those hoo hoo opener uppers, you know the sideways duck bills that spring open so you can get your arm up in there.

Oh, you're looking for those? I'll have to find something...........interesting for y'all.

I have an electrolytic pool chlorinator with flat plates that looks something like that.

But, no. Not a chlorinator, but maybe a water splitter?

Is it an electrode for a de-salination unit?

@gynojunkie A whole bunch of no. Not even a single close.

That was a harsh put-down, my man.......
