I have attached a screen shot of the bottom of the same FUS5. There was no problem slicing this portion. My filament width is set to auto (which is 0.48 in S3D). You can see there is a gap between the outer wall of the part and the inner wall that lines up with the inside of the Tab. My tabs then broke off with the skirt due to the thin bonding here. I had tried every type of thin-wall option with gap fill in S3D to get the space between the 2 outer walls and that inside Tab wall to fill with no success.
