Champagne glass, approx. 140 ml
I printed the glass with
shell: 1.2mm
infill: 100%
layer height: 0.1mm
print speed: 30mm/min.
printing time: a...pprox. 16 hours
With these parameters it looks perfect and it is watertight.
I tried it with shell 0.8mm and infill 30%, it also looked good, but this was not watertight.
