I tore my hair out making sure everything was aligned correctly and touching just right. Some letters just would not union unless paired with 1 or 3 others in just the right way that made no sense. And it wasn’t just with nameplates.

Sure that assumes user knows what Non Manifold is you and others know from experience. Current messages is more generic and straight forward.
