3D-Printed breathing mask

A free simple breathing mask composed of 2 parts : the mask itself and a plugged cap to hold a tissue filter or whatever you want (you choose). Needs to be scaled to the good size before slicing and 3D-printing. Please use PLA for recycling possibilities. Thickness: 0.2mm (can be scaled on Z)

********************************************** WARNING ***********************************************
- ACTUAL VERSION : 0.04 (Alpha)
- MASK STATUS : NOT USABLE - PROTOTYPE
- USE AT YOUR OWN RISK

Hi, I write this post on the sunday 22nd of march 2020 where 1 billion people are confined.

I do some 3D modeling since ~2006 and 3D-printing on RepRap since 2013.

Pros:
- 0.2 mm thickness which makes it flexible (scalable on Z) (argument that makes this design unique for the moment)
- Weights ~3 GRAMS on the current version
- 3D-Printable at home if you own a 3D-printer
- you can 3D-print it for your familly and neighboors
- you can modify it using the .blend file (I'll document the process a bit)
- it's free to download right now in the next clic
- if you 3D-print in PLA it will be Bio-degradable
- [...] to be completed

Cons:
- There is no filter obviously this part has to be added by the user. That's why the AFES Chile warning does not concern this prototype
- Security norms other than filtering (skin contact problems etc. - still searching : documenting myself on this and got some informations from this group : https://www.facebook.com/groups/opensourcecovid19medicalsupplies )
- Is the shape good for ALL ? no, it needs various shapes ! (made from version 1 not this 0.04)
- Needs elastics and inside protection so there's no direct contact with the skin
- Material used: is PLA good for this ? what about other materials like ABS ? main argument about PLA is that it's BIODEGRADABLE so I strongly recommend it, let's not forget our "plastic problem" aka "8th continent".
- [...] to be completed

During the coming days, I'll be working on version 0.0x but until the final release 1.00 please use a professionnal mask or use at your own risk.

If you decide to fork from the .blend file, please DO SO ! This is only a concept and not a version 1.00 which means it's not perfect at all. It's also a demostration of what can be done and may give ideas for other purposes.
This mask needs testing in various sizes and heights (Z), and some optimization.

I'll be giving names to zones of the mask : the nose, the elastics plugs, the air-filter-hole, the filter-cap (second part 3D-printed at same scale).

This part is the nose part. I invented this shape of "buttons" or "pins" but it's not perfect either, I'll maybe make them bigger...

PS bis: I don't agree with this warning : ANY protection is better than ZERO protection.
