thingiverse

This is a flexible connector designed for use with DIY face masks, allowing users to connect and adjust the elastic easily. To secure the connection, simply lock it into place. A clasp version of this connector has also been uploaded, featuring a hook-and-eye design that makes it simple to attach and detach as needed. The intended application for this connector is for face masks that encircle the head, rather than those that go around the ears. This type of mask is typically worn by healthcare professionals over their N95 respirators. Hundreds of these masks have been made, each one designed to provide reliable protection for medical staff working with patients.
