I was printing a part I made and found a defect in the STEP conversion in OrceSlicer. The defect isn’t as bad as in the post I linked to in the post above, so it is not that noticeable when sliced. I made a high resolution STL in Fusion by right-clicking the component and selecting Save As Mesh. I made a custom resolution which is similar to high, but a little better.
The one on the right is the STEP. It makes the curve smoother at the bottom part, but has some dents on the corner at the top part.
