I liked the veroni case by Link Designs. However the rounded sides led to some artifact issues near the bottom of the case. Likely due to the slope of the sides at that point. Therefore, I combined the Link Design case with the one by Daniel Schultz. It has a more square side shape resulting in an increase in TPU print quality in that area. I printed at 0.15mm layer height and 10% infill to keep it flexible. I also used painted on supports in the small gap areas on the sides, but this may not be necessary depending on your printer and/or filament.
