Respira Mask to P3 R Filter Adapter

Adapter for comfortable half-masks Respira Compact (by Nanologix Corp.) and commonly used antiparticle filter P3 R (by AVEC). My next quick on demand design for doctors️ fighting covid-19. In my case it will help anesthesiologists in overloaded Czech hospital. 

Functional prototype of adapter is 3D printed from quality PETG (by Fillamentum), but use a sterilization-resistant thermoplastic suitable for the selected (!) hospital ward.

Thread sealing: Use the original seal (circular cross-section) from the filters supplied with the Respira mask (on the side of the mask) AND a flat common rubber seal into the NATO Rd 40 1/7" thread (on the side of filter; outer diameter approx. 36.7mm; inner diameter approx. 32.5mm; thickness around 2 mm). You can print both seals from durable flexible material (TPE, etc.) in case of emergency.

Note: This solution IS NOT specifically certified. Use it where medical supplies are lacking.
