Bandana Face Mask Exercise Breathing Aid

When exercising with a face mask the fabric is prone to pulling against your mouth when breathing in, making breathing difficult. This device maintains a space between the upper lip and fabric, making it easier to breathe freely.

Print instructions

Print using PETG for toughness and flexibility. Settings used were 0.3mm Draft using prusament PETG. Print time about 1 hour on Prusa I3 MKS3S. See the screenshot. The part may need to be flipped so the correct surface is touching the build plate. Supports are needed under the protrusions. I have not tried printing with PLA, but it will probably work OK. It will result in a stiffer, more fragile part.

NOTE on SCALING: For my face, I scaled the widest dimension down to 145mm. You may need to scale the other dimensions as well for a best fit to your face.

There are various ways to wear the device. Elastic can be used to secure it behind your ears. Fabric or rubber elastic bands can be used across the front of the device to attach it to a mask. In the case of the attached photos, a fabric bandana is secured over the posts with slotted fabric elastic band. I found this to be the most comfortable option. I first placed the device over my face, tilting my head slightly back. Then tied the bandana over it. Lastly, I bunched the fabric over the posts and secured it with elastic band as shown. Be careful if using an actual rubber band. If it slips and snaps loose it can snap against your face.

I have tested this device while running in Los Angeles, where a recent ruling requires face coverings to be worn anytime while outside of your house.
