Breville Bambino Headspace

Hello! Would some kind person with a Breville Razor tool and a set of calipers please measure the depth that the Razor sits into the portafilter?

Those of us with new bambino standards did not get this tool and there is very little information online. One person on a Reddit thread said it is 7mm of headspace that is being measured, but I think a lot of people cohld benefit from a hard confirmation.

If we know the headspace, we could make our own gauges :)

Thank you so much!
