Precision Edge Marker

I've made this tool for my father use. He needs to draw a paralell line to the edge in some woods, so with this tool (with the screws) he can adjust the distance of the line to draw.

I've made a lot of version, but we have found the full functionality in the last one, named as "...V1.1(Linear).stl", but i uploaded all version by the way.

You are going to need 4x M3*12 screws for adjustament of the marker.
And the tools supports markers between 9-10mm.

I appreciate your likes (are free :)), and i know that it was usable for you.
