Stealthburner Printhead for Rapido rear CW2

[therm_virtual0y]

I printed the Rapido rear mount for the CW2 and have some spots on the lower left and right that looks like I had a clog but the rest of the print looks fine.  I reprinted it after verifying my extruder was ok and same thing.  I then looked at Cura slicer and saw that the holes are there in the slicer so the print was doing what the code said.  Not sure if this is a STL error or CURA 5.3.1, but I have not had this problem on any other prints.  Normally I would get an error if the STL isn’t watertight but I didn’t on this.  I am able to get Cura to fill the holes via the setting (remove all holes) but then other parts on the build plate that are supposed to have holes get filled.

any help would be greatly appreciated

Seems like a setting or Cura thing to me, I just checked the original in SS and it looks fine to me.

It is a single wall at some point, but not even a thin wall, a normal wall.

Thanks.  For some reason the resolution was set to wrong.  Fat fingers I guess.  Thanks for your time
