When I export a simple drawing and import to prusaslicer i get different results. The stl results in much larger diameter circles while the obj results in slightly more accurate size circles. I have attached screenshots to show. The obj is the one on the right. I have checked and changed inches and millimeters in both export and import. The sizing once printed is off from the design significantly. 1-2mm wrong on circles and more on width and height. Not sure what to do or check.
