Tripod-top plate

Inspired by something Mattheu Stern mentioned in a recent video, this is an arca-swiss compatible flat surface to put things on. A bit larger than his, but I just picked a reasonable looking size.

He mentioned using his for 3D scanning small objects, but you could use it for all sorts of things, like when you're out somewhere, have a tripod handy, but nowhere flat/clean/dry to put anything down, for one somewhat strained example.

I thought 'that's a neat solution' and had a quick look to see if anyone had posted one, before I went and reinvented the wheel*. Apparently not, so here we are.
