I have been looking for a 3d printable mask that was easier to print than what is currently available. This is my design which requires no supports to print. Please review. The mask would be put together like the MUSC mask utilizing foam sealer and hot glue if needed to make any seals around the air filter and the tube that is inserted into the mask.
