Sony Action Cam lens cap and protective cover (with notches)

This is a remix from cenkaetaya desing https://www.thingiverse.com/thing:1995096

The sony camera has a couple of grooves on top and below the lense used to hold adapters, so I modified with notches that fit in those grooves. It click in place by inserting tilted with bottom notch first..then you just click on in a smililar motion as putting on a hat.

With this modification the piece does not fall at all even in intense motion/action.
