Cannula Box Cover/Protector

My mom is on oxygen, and when she switches from her portable oxygen concentrator to her main oxygen concentrator, she is always left with leaving one cannula out in the open to collect germs. So I built her a quick box that allows the nose piece of the cannula to sit inside, and it snaps closed. This ensures it doesn't accidentally open and is slim enough to fit in the pocket of her portable bag, a pant pocket, or purse pocket when not in use.I wanted to share in case anyone here is running into a similar situation or knows someone who is, and would like a simple solution to help keep their oxygen cannulas protected.It prints in one piece and has a print-in-place hinge. I grab the hinge with each hand to help support it, and then bend it to break the hinge free, and it closes shut.If you have any issues with the file, please let me know, as it has gone through a lot of iterations, and I just want to provide folks a little help with their medical needs if I can. Happy Printing!!
