>>10089635I leave ~0.1mm gap in between parts, let the cement get sucked in there, check that the entire length of the seam is filled with cement (add more if needed), wait ~10 sec, then squeeze the parts hard enough so the melted plastic comes out along the entire length of the seam and that usually does it.
If your gap is not completely filled with cement or you didn't squeeze the plastic out of the entire seam, that's when you start having problems with seam quality.
