Calibrating functional prints with 0.8mm nozzle
My MK3S+ has been working well with the stock 0.4mm nozzle, but as I am doing larger functional prints I've started using a 0.8mm nozzle (E3d brass). I am finding that the resources I've used for calibration have less to say about how to adapt to the larger size, so I'm struggling to understand how to improve my prints. Here's an example print that I have three questions about (photos here):
- Why are there holes in the print at the intersections between seams? I can literally see through the print in three different spots...
- How do I address the zits and blobs on the interior? It seems like these are overextrusions?
- Why does the top layer look like it is underextruded? The seams don't quite come together...
Details:
- Filament: Prusament PETG (probably a little wet, drying it right now), using PrusaSlicer's Prusament PETG profile
- 0.55mm DRAFT print settings, with 5 perimeters and 15% fill
- GCODE file attached (Can attach model also if helpful)
What should I do to troubleshoot this print and get happy with large nozzle life?

It doesn't look like the GCODE attached. Here's a dropbox link to the GCODE and .3mf files: https://www.dropbox.com/sh/bl9e71nz7dmxwgf/AAAUjs-zgubMaQVTBlHblovRa?dl=0

The blobs and zits cleaned up well with dry filament. Still not sure about the see through gaps and apparent under extrusion on the top layer.
