Parallel Marking Gauge with Metric Scale

This is a sliding parallel marking gauge with a metric scale. It is very usefull in wood working to draw lines parallel to an edge.You can download two sizes: A small ruler with a range of 150mm and a large one with 250mm. The small one fits the A1 mini, the large one needs a 256mm build size bed.The ruler can be locked in position by a printed M12 bolt. The scale is quite precise but you need a calibrated printer for that. As most of you have a Bambu Printer, this will be no issue as these printers are very precise out of the box. Print preparation:Make sure that your print bed is clean and grease-free and use a quality brand filament. Calibrate you filament otherwise the scale will be hard to read and the slider can jam. Print settings:For all threaded parts use the 0.12mm layer profile. Turn on supports for the bolt but make sure that you do not use supports in the threads. Both threads must not have supports.The ruler and the slider should be printed with the 0.2mm layer settings w
