TPU Fabric Mask Frame

thingiverse

I require a specific aluminum strip, measuring 100mm by 5mm with a gauge of 30 (0.27mm) for a nose clip. I've sourced this type of material from roofing repair sheets available at Home Depot. Initially, it's necessary to sew a pouch into the fabric to insert the nose clip strip. To do this, I fold my fabric around an old construction face mask and use tape to maintain its shape before sewing on the TPU frame.
