Inspired by several of the nose clips for face masks that I've tried from thingiverse, I've created my own design from scratch. Easy to insert and comfortable, it prevents fogging and discomfort in the eyes while encouraging a tight, proper fit for the face mask.
The surface is drafted outwards like the nose, there are many chamfers/fillets for added comfort (no sharp parts against your skin). The clips are both robust at the root and easy to insert and lock in place.
I've printed in PETG for increased durability but any material should be fine. Use proper settings for good layer adhesion so you get a strong part.
