Face mask strap (York & Victoria in Guelph)

During the pandemic, someone on Wood St was 3D printing the straps which keep face mask elastics off your ears. I gave mine to a health care worker, but am flying to visit an elderly person and want to mask the whole way. The strap I currently have is really flimsy! Yours were FANTASTIC! Do you have any left? I would love to receive one, and possibly one for my sister too.
