Need a dimmension to build a squaring tool

Hi,
Is somebody knows the exact vertical spacing between X and Y conduits for the 25mm conduits buid?

I found 2.5mm when I try to determine it with Fusion 360 but I read 2.1mm somewhere on thinghverse comment…
thank’s

I’m measuring it at 2.5 mm also. And just to confirm, this is the “F” version.

The Burly “J” version (1 inch, 25.4 mm OD) has a 2.1 mm gap according to my measurement.

Ok thank’s
may be I read 2.1 in something related to the J version
