The nose clip is supposed to prevent fog on eye glasses, but it seems too deep for my nose, leaving a gap. I still have to test this.

The strap that goes at the back of the head was hugely popular on Thingiverse (it was published back in March 2020). Its big shortcoming is that it tends to lower naturally on the neck, and the mask’s elastics then rub against the top of my ears. I’m thinking of designing my own version with 2 widely separated bands, one that would sit at the nape of the neck, providing a stable resting place; the other higher on the neck. Also make the hooks more widely distanced to be sure to clear the ears completely.

I printed them at 0.40 mm layer height in ABS, my printer is old and slow.
