Proposed Strap Attachment Solution #1

Open DudemanJones opened 4 years ago

DudemanJones commented 4 years ago

Respirators and face masks need at least two straps, in order to properly balance pressure along the entire seal. Based on your initial strap attachment, I have made a 'K-Strap' that fits on a 200mm square print surface, and provides 4 attach points.

With this, I am able to wear the mask hands free with a good seal across the entire face. This also helps to relieve pressure against the nose, which can become uncomfortable. The K-Strap STL file is attached below.

Did you edit this with Fusion by any chance? Could you send me the cad file?

DudemanJones commented 4 years ago

Tinkercad actually. I'm not too experienced in full CAD modeling.

Can you share anyway? -- I'll see if I can import it or I'll just publish it as is. It's important to me to be fully open-sourced.

Respirator mask K strap OBJ.zip Hi fabien.

Tinkercad supports STL, SVG, and OBJ export. You can reference it at this link. https://www.tinkercad.com/things/gLNEm04YfIl-respirator-mask-k-strap

For convenience, I've also attached a zip file with the OBJ and MTL files for the K Strap.

My apologies, as I don't know how to use any other CAD or modeling tools. I hope this helps.
