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.

I used Ubuntu Touch for one year on a 2014 OnePlus One phone, until its touchscreen crapped on me last Fall. The phone was already pretty banged up when I got it from eBay. This gesture-based UI feels natural, very quickly.
I've been testing Plasma Mobile on a Pinephone, as well as Mobian/Phosh. Hoping I don't start a flame war, but I agree Plasma Mobile feels like an Android knock-off... So far, Plasma feels very nice though! Much more than Phosh, which feels bland. But Mobian/Phosh seems the most stable of the two, there are apps missing as well on Plasma (a system monitor for example).
I love Lomiri, but Ubuntu Touch has shortcomings by design that aren't suitable for me. For now, Lomiri is only available on Manjaro (apart from UT), and is still in Alpha stage. I'm hopeful it will be ported to more distros in the long run.
