EPAP - sleep apnea and snoring aid

EPAP - Expiratory Positive Airway Pressure is a treatment device for sleep apnea that attaches to the nostrils and can serve as an alternative to CPAP.
It can also help reduce snoring, which it has done for me and my wife.

EPAP provides minimal resistance on inhalation and a positive pressure on exhalation. This opens the airway when exhaling which makes it less likely to collapse and interfere with your breathing.

Please give the device a few nights to get used to.

Instructions.

Print part 1 and part 2 with a durable filament. I used PETG.
Print part 3, part 4, part 5 and the optional part 6 with a flexible filament. I used tpe-83a.
Print all flexible parts one by one to avoid stringing.
Part 4 must be printed on a non-textured surface to ensure a complete seal against part 1.

The seal surface on part 1 must be ironed and smooth to ensure complete seal against part 4 when exhaling. Sand if necessary as the ironing feature doesn't always leave a perfect surface.
Use the part 5 - seal test (without the restricting hole) to check if the parts seal completely.

The nose piece (Part 3) will probably need to be modified to fit your nostrils. Also make a mirrored part in your slicer before printing.

Part 6 is optional and can be used to connect both devices, but will most likely require modification to fit your nose.

The hole in part 4 can of course be changed to better suit your needs.
