Marking gauge for folding rule / Streichmaß für Zollstock

This is a simple tool aid for woodwork. An adjustable marking gauge that will help you draw a line with constant distance to the object's outer edge.My design uses a melt-in M4 brass nut by Ruthex to hold the screw, thus it won't wear off after a few dozen usage cases. The actual dimensions of your folding rule may differ, so I have designed a wide opening. This may result in an unprecise angle of the inserted folding rule.Feel free to adjust the dimensions in the OpenSCAD file according to you
