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 or a pre-heated nut for insertion, but then it will be reliably fixed.
UPDATE:
I have added a further knife-head which supports fixing the knife blade by a screw, inserted either from the left or right side, so that the minimum cutting distance of 10mm can still be reached. Insert zwo M3 nuts from the top, print a further knob and insert a M3x10 screw there. Secure with CA glue if needed.
