Kardia Keychain Holder

My daughter is a registered nurse. She monitors my EKGs every morning since I had my stroke 2 1/2 years ago. A few days ago I started to have an episode of Tachycardia. I was in the garage and it took me several minutes to get my Kardia 6L which I normally keep in my bedroom. She suggested I keep it with me at all times. So I did a 3D scan of my 6L and made this case. The case is pretty snug and I doubt the device will slip out on its own. With the addition of the hole for the ring, the ring adds an additional stop to prevent the 6L from coming out unintentionally. I suggest printing it with PETG which offers superior strength, flexibility, and heat resistance over PLA.
