N95 Mask Straps - 3M Half Mask Respirator Style
thingiverse
I had some expired N95 masks with rotted straps - and I really like the adjustability and comfort of the 3M half-mask respirator straps. So I created some parts that I can retrofit to my expired N95 masks to work just like the 3M half-mask respirator straps. These are designed to pair with 13mm wide and ~150mm long elastic straps. I've been using them for over 2 months now without any issues or signs of stopping.
