Snorkel Mask Charlotte Valve EZPrint, Horizontal PETG print with cable tie slot (Emergency C-PAP)

thingiverse

For extreme emergency use of a snorkel mask as a C-PAP mask, the Charlotte valve is remodeled to print horizontally with no supports (depending on your bridging capability). The print weighs about 60 grams. Optimized for printing in PETG, we are printing them in natural PETG. The pipe sections under test show strength. We do not know if the tubes are strong enough when printed vertically in PLA; you need to test it and consider the layer adhesion strength that could be an issue. A tighter fit with no wobbling is achieved. An integrated cable tie slot keeps pressure on the clip, securing it firmly on the mask. Click it into place, run a cable tie through, and tighten. No supports are needed, depending on your machine's bridging capability; test first. It uses a 19mm ID PEEP valve and 22mm ID hose. Make sure to modify the disk valves in the mask according to the instructions in the video. Some masks that have been donated to us lack an o-ring, so we are printing the seal in TPU. The file is attached; if your mask still has a good seal on it, you do not need to print one. Tested with no air leaks on multiple masks, including Tribord and Thenice brands so far.
