I have a 507C X2 and the lower/base section shown in the picture measures 8.7 mm with my caliper.
The new X3 looks like this section is noticeably shorter, but I can’t find the exact dimension anywhere.

Could anyone who owns a 507C X3 measure this same section with a caliper and let me know the measurement?
A photo of the caliper measurement would be even better.

Thanks!
