I re-added the image. The external image embed doesn't like google photos it seems.
> Can you use less infill? Or go into the advanced settings and increase the layer height?
I can, but I wanted this part to be stronger. I've used this infill amount before. Maybe I'm crazy but I could swear the infill is 'thicker' with UM3 rather than just more lines.
R/e glue same here, but my first layer was perfect in this case. It was the higher ups which went to pot.
