##Updated March 3rd 2020 2pm est.

** USE AT OWN RISK if your smart and make sure this config is air tight it is better.

Update March 9th 2020 -

Version 0.02 Large 3M® 6300 adapter part, Designed to print fast, I’m currently just under 2hrs per part

Thinner walls, tilted Mouthpiece adapter for better fit.
Optimized for printing. 0.4mm nozzle. 0.5mm lines and parameters width.
2 parameters with alternating 3rd
20% fill – grid – connecting lines.

Works in progress, source files (STL’s) to download for free and no login or other requirements on my personal site. http://gallaghersart.com/page/airtight_adapters_for_medical_masks_and_face_respirators

Have more designs just need time to print and verify.

I have been working on these designs a few years ago and have plans for commercial plastic injection molded add-ons / that enable disposable and face respirators to be airtight.

They require a scuba mouthpiece and nose clips. Once installed ALL air goes through scuba mouthpiece and through air filters, NO leakage from side of masks or for people with beards (like myself and why I created these, so I do not have to shave my beard).

Due to COVID-19 I’m posting my 3d prototypes for personal use. With hopes of finding support and funds that I have no way to get myself.

Please donate so I can purchase all other types of disposable and half/ full face respirators and find the best nose plugs and mouthpieces. ALL proceeds will go to this, my time is donated at this time. See my website for donation and future kick starter link

My plastic injected mods would-be one-piece adapter with mouthpiece. Washable and reusable. Just swap out masks/ air filter.

Currently I only have the 3M 6300 Large half face mask. With donation I would need 3 of each face mask to build adapters. (1 to cut up, 1 to use as protype, and one that will have final modifications done to them). I could also use one of the Super high-resolution 3d scanners that is capable of reverse engineering the units, so far, the price tags for these 3D scanners is $25k -to - $50,000 for the units. I hope someone out there may work with me so I could borrow a scanner. I live in Massachusetts – so if you have one of these please let me know if we can work out some things for temporary use.

This is ongoing and more mods will be posted once I have printed them and verified, they work. Also, versions that people can just use what ever fabric/ filers they have as a last resort.

Please note at this time use at your own risk. I can not be liable for anything. And use in face respirators may void your warranty. But when used correctly these only make the masks and respirators truly airtight.

Currently I’m using “magic tape” that is double sided and 2mm thick for my 3M 6300 face mask. This tape is reusable by washing with water then air drying. (still testing this myself).

With the face respirators I planned the final version to be single silicone piece and the pressure from the face mask should keep things airtight (not verified yet, need more masks to test.) If not, magic tape may be end solution (if you make magic tape I need some that has backers on both sides of tape so I can more easily cut to correct shape – please contact me)

My end goal would be mods that people can 3D print themselves across the world. And Commercially made injection molded part mods that can be purchased at a low cost. Also, a cardboard version that can be given out in emergency situations at a super low cost, while using cheap disposable masks.
