Cutter Ruler #2

This adjustable ruler is an improved version of my previous ruler, based on user feedback. It supports dragging a cutter knife along a border in a defined distance and due to its now symmetric parts it is fully adaptable to the actual situation..
The ruler now has distance marks every 10mm which are more visible than with the previous version.

Glue M3x12 threaded rods (or a screw without head) into the slider and ruler arm and insert M3 nuts into the fixing knobs. You will need some pressure
