I'm so unbelievably proud of myself over the silliest accomplishment. For the first time ever (and I've been doing this a looooonngg time.. close to 2 decades now)... I've designed, 3d printed, and fit a trim piece *insert* ... On the first try. No revision to the CAD model for hole alignment, no revision to print settings, no reprints to account for shrinkage,expansion, spaghetti, or adhesion... All the clip holes lined up exactly.. Even the surface ironing came out well.
