i printed the model in separate pieces, not all on the same print. I recommend printing with support everywhere and a brim platform of at least 10 lines, as mine has slight droopage in places seen in photos. also recommend printing at a better layer height quality and a slower print rate, even though mine came out great. print time is total time of parts. the mouth piece took 1.5 hrs, the inserts each take about 1-1.15 hrs, and the bubbler body about 4-4.5 hours.
