I've printed many face masks but this version was the best among all, due to many reasons: - It's very suitable to face shape because it was 3d scanned and edited by the designer. - It can be easily 3d printed and it's made of 2 parts only (without any post processing). - It can make full seal around mouth and nose (with a pad)
According to the designer, the design was inspired by : NanoHack: Open-source N95 Mask https://www.thingiverse.com/thing:4231069
the original design : https://cults3d.com/en/3d-model/tool/masque-de-protection-covid-19-epi-equipement-individuel-de-secours
My modification was: - Changing the cap shape by using Sketchup, so that it can be easily opened and closed without the need to remove the mask, because the original cap is flat from the outside. - Also made a grove around the cap so that it can be hung when changing the filters in a hurry.
*Note: - For Women keep the scale 100% - For Men Upscale to 110% ~ 120%
