It's bizarre that there is not included lens protection for such incredible camera as Osmo Action.

But hey - why we have 3D printers? So just another lens cover for DJI Osmo Action was born as I did not found there one that can printed with hard plastic and which will stay firmly enough in place...

If you want nicer looking one and you have plenty of time, then print it with thinner layer height possible. My first print was with 0.2 mm height and looks quite coarse, but printed only within 6 minutes and completes it's task very nicely...

As thinner, then better

Depends from resolution, but probably no
