These mini calipers offer a great way to make quick measurements while out and about. Although a simple design, it can be quite useful.

About the design:

The keyring on the back keeps the measuring head securely attached to the body. Measuring marks are every 1mm, with longer marks at intervals of 5 and 10 millimeters. The total measuring range comes in at a little over 50mm.

Disclaimer:

As this design is 3D printed, measurement marks are not guaranteed to be accurate. While an effort was taken to create the file with exact measurements, 3D printers are not always precise. Measurements taken should be assumed as estimations rather than exact dimensions.
