Set the resolution `EXPORT_DPI` of your 3D printer's screen and object width `TARGET_WIDTH_MM`. The height will adjust proportionaly. The thickness `THICKNESS_MM` of the model can be adjusted as well. Make sure you set the exact width of your model in `TARGET_WIDTH_MM`. Take the width from the outset measurement shown in the KiCad. The height will adjust itself proportionaly. The thickness `THICKNESS_MM` of the model can be adjusted as well. Set the resolution of your 3D printer's screen in `EXPORT_DPI`.
