A card with a simple caliper

It is a design for a card (in the size of a credit card) with a simple caliper. It is easy to print (around 21 min) and it does not need printing supports. It is composed of three parts and two of them can be easily glued together. For the measurements in millimeters, the easiest approach is to print (on paper, using a laser printer) this simple ruler (https://shorturl.at/Ffw23) and to paste into the moving part.
It seems that this is the first design in Thingiverse for a card with a caliper.
