3M mask - ventilator filter cap with recue logo

thingiverse

This adapter enables use with just one filter from a breathing ventilator. You will still need the conversion setup available at https://www.thingiverse.com/thing:4239221 in order for this piece to function properly.\r\n\r\nA crucial note: This connector serves as an alternative to the original and certified parts, but it has not undergone clinical testing of its seal. Its acceptance by some individual doctors is based on their own evaluation. From a purely logical standpoint, however, the tight fit should provide a full seal.
