NeoCaliper Kit

I thought I was ordering a ready-to-use caliper.

Solid as a rock.
This is extremely good quality, well developed design and features.
It’s expensive but well worth every penny.

Great add on. Feels sturdy when installed. My only gripe is that the Inside Measuring Jaws are quite wide. 7mm almost all the way to the tip. Makes it impossible in fit those jaws when measuring sub 5mm diameters.

Still, if you have the ruler already, probably the most useful add on to get.

It appears that the caliper kit is a fairly good one but difficult to fit properly..took far longer than expected when it finally decided to snap in place.

Great addition to the standard ruler
