This is an .stl file for printing a rubber dam frame, with an aerosol removing suction inlet in the lower frame member. For description and intent please see the youtube video. At time of publication an instructional video is still to be published. I am working on it, but it is challenging due to our local lock down restrictions.The main part is the frame itself, plus a couple of connectors to fit various size high volume suction inlets. The idea is to add a flexible pipe with smooth internal surface to the coupler, and connect that to the bottom of the flattened chalice in the rubber dam frame
