COVID-19 emergency: Decathlon diving masks become C-PAP for respiratory ventilation _ remixed

thingiverse

A friend of mine recently drew my attention to a remarkable project on Twitter from @blueman52: "COVID-19 emergency: Decathlon diving masks become C-PAP for respiratory ventilation." Given that I already own some Decathlon masks and live near the main infected area in France, I'm eager to produce a batch to aid our local hospital. As I attempted to print the original files, I found them somewhat theoretical. While a perfect 3D printer with SLA technology would likely yield excellent results, my FDM printer's quirks led me to make some adjustments. Here are my modifications: * Thin walls are acceptable, but printing orientation significantly impacts their stability. Depending on the chosen orientation, pipes may become fragile, and the small top tab is easily breakable. A 45-degree orientation strikes a balance. * To accommodate 45-degree printing, I created a new profile for the Dave valve to improve its adhesion to the bed. Excess plastic can be trimmed if needed. * The fixation tab was too loose, so I reinforced it. These tweaks should help others who are inspired by this project. I'm grateful to the original author for their work; my changes were minimal and built upon their foundation.
