Caliper adapter for measuring hole distance

I quite liked the original design (https://www.printables.com/model/396136-caliper-attachments-for-measuring-distances-betwee) to adapt my standard digital calipers to measure the distance between holes which I always had to guesstimate before. However, it was a bit too tight for my calipers and that design has a quite large minimum measureable distance of 17 mm. So I made the hole a bit wider (3.3 mm), decreased the thickness to the center (reducing the minimum distance that can be measured to 8 mm) and added some holes to improve the resin printability. The accuracy is really quite good with these adapters: The holes in the PCB on the picture are supposed to be 25.0 mm apart.

There is one STL with holes for resin printing and one without for FDM printing and you can just modify the thickness parameter in the F3D file if the model doesn't fit on your calipers (assuming the shape of the tips is the same otherwise, though that seems to be pretty standardized with the calipers used by most makers).
