Scuba Mouthpiece

It used to be that you didn't swap mouthpieces on rental gear - now you do. I got to thinking this would be a good thing to make on the resin printer. I printed it in a flexible resin. I've not tried it on a dive but it looks the business and fits the regulator. Keep in mind that resins are toxic when uncured and many are likely toxic when cured. Putting something toxic or even just irritating in your mouth is inadvisable. Also, some resins might react poorly to high O2 content in NITROX...who knows. Think carefully about your resin choice.
