Height Gauge Marker

This is a simple height marking tool that can be used with a pencil to draw height markings on a cylindrical surface.
It stores away in pieces to save on storage space.
I used a 13mm wooden dowel as the pole but I have included a pole file should you wish to print your own.

Requires 2 x M5x0.8 screws to act as clamps for the height and the pencil.
