Technical Dimensions of Creality Falcon 2

Hi, I have a Creality Falcon 2 12W Laser Engraver.
I want to make some template metal sheets for different projects that I can easily switch between.
I know that the product size (frame size) is 664x570 mm as specified on the store page. That means my sheet will be around 680x600mm so it’s bigger than the frame itself, as it will be underneath the whole frame.
What I couldn’t find is the dimensions between the foot screw holes (see drawing) so I can drill 4 holes into the sheet itself for positioning purposes.

If anyone knows these dimensions, it would be extremely helpful.
Thank you in advance!

On my Falcon 2 22w, this is what I see:

The rubber feet on the legs are 24.8mm in diameter on the bottom.
