UPDATE MARCH 28TH, 2020: Uploaded original FreeCAD files (Fcstd) and improved the adapter with a GoPro mount available! YELLOW JACKETS! Protect yourself during your Saturday outings against any physical damage to your face or respiratory problems! This adapter is designed to attach a gas mask filter with standard RD40 screw thread (40mm X 1/7") on an Easybreath snorkeling mask from Decathlon. Its Polycarbonate screen provides correct protection against losing one eye or several teeth. Two versions are available for printing: one for flex filament and the other for PLA / ABS, allowing you to use your mask during the summer without damaging it. Simply block the external holes on top of the mask (see picture) to prevent expired air from blowing into the filter.
