Holes in walls on thin Gridfinity stuff. Slicing error? Input Shaper?
I've started down the Gridfinity rabbit hole. First container was on of the original Zack ones. Double walled & used a lot more filament than I was expecting. Next batch was a platter of 3 vase mode containers. All the vase mode ones have a hole on one corner each. I didn't check the orientation on the platter before I removed them. The one with multi-layer walls & a curved bottom has several holes where interior features hit the vertical surface.
I'm in the middle of another batch of vase mode containers which will be chugging away all afternoon. I re-sliced a 3rd batch using a non Input Shaper profile, but won't kick it off for a bit. Slicing in PrusaSlicer 2.7.1 looks fine with none of the artifacts showing. I'm use to the zits at the start/stop of every layer, which are irrelevant to these functional rather than cosmetic parts. But these are structural flaws.
Any suggestions on stopping these holes?

Same issues today trying non-InputShaper profiles. the bad corner moved from back right to front right and some are almost ok, others are really bad, as before. Ran out of Overture grey PETG so switched to black. The old MK3s is chugging away with some PLA just fine & no signs of these issues from the same slicer. Only my XL having issues.

How thick are the walls. The look very thin. The holes look like they are along the z seam. Maybe up the filament temp a little or moving the seam to a different place. Or making the wall a little thicker.
Wall thickness - or rather, extrusion width is likely to be the issue.
Carefully designed prints for the Mk3 series &Mini will usually assume 0.4mm nozzles extruding at 0.45mm width, they may even be tweaked to take advantage of the size. The XL's default nozzle is 0.6mm extruding 0.65mm wide; in consequence some of the most carefully designed parts may need reworking - or fit 0.4mm nozzles to your XL.
Cheerio,

You should print them in vase mode if they are specific vase mode containers.
