Nose Clip for anti COVID mask
thingiverse
Here is a device that can be glued with hot glue onto a mask to improve the fit around the nose. There are a couple versions here, with the A-version being somewhat thicker, which might offer less resistance to springing open and compromising the fit. If you find this useful, but have a suggestion for modifying it to fit some people better, please let me know, and I'll add another version(s) right away. Update 4/17/21 I added a version that fits tighter on my face and is twice as thick in the arms.
