Hey Nate. I didn't have the settings of that written down (which brings the idea... can an option for saved favorite settings be added? That way you can quickly go back and generate .stl's if you lost previous files maybe?) so I went about creating something close. That image was my second mount. The first was even worse. I think I had used a fillet on the base. Sorry I didn't save a pic of that one.
I created a new one and the mesh shows a very similar issue in the same area. Every output I pull into Cura 4.13.1 (my slicer) I get a warning about it not being watertight and possible printing issues. The image I first posted was from Tinkercad where I just imported it to check it out real quick.I have screenshots I'll add.
