Modular respirator mask - strap

thingiverse

I created a more flexible design by making the TPU-based straps too rigid for everyday use, so I developed an alternative solution using a 20cm x 0.8cm strap instead. To assemble this new design, simply print eight strap fasteners and four TPU straps, then create loops with them and secure everything together using elastic bands or wires by attaching zip ties.
