This is a variation of my "Robust Digital caliper wall mount" to accommodate "hole to hole / edge to hole" calipers. There is no offset just straight across level arms to hold this type of calipers.

I used command strips to stick to wall. The other calipers shown have been hanging there for a few years with no worries of them falling off from the adhesive wearing out.  If you don't trust the double sided tape you can screw it to the wall too.
