Breathalyser Mouthpiece

thingiverse

My homebrewing club has a breathalyzer unit with detachable mouthpieces that we're supposed to return and reuse, but in all likelihood, we're too intoxicated to remember where they are. To avoid this problem, I replicated the design so we can print additional units. Unfortunately, I don't know what model of breathalyzer we have. Print the design with the large hole facing the print bed. Since it's a simple design, no supports are required. I printed mine with a brim, but I always use a brim when printing anything - I'm totally brim-obsessed!
