DIGITAL TYRE DEPTH GAUGE MOCK-UP

This model is intended as a design aid rather than a printed object,  although the files are provided to do that.  

There are many uses for tyre dept thread gauges, and I thought since I have it already modelled, it might be useful for someone in the process of designing a device that incorporates it.

If you wish to print it for whatever reason, the two parts fit together and the probe has been sized to substitute an M3 machine screw.
