GoPro Plastic Bottle Cap Mount

GoPro Plastic Bottle Cap Mount
The idea is to use any plastic bottle as a grip/stand/floaty at the same time.
I saw plenty of solutions here on Thingiverse as well, but I did not find any of them perfect.
The concept is brilliant, you get basically a free GoPro grip, which at the same time makes your camera float. Though a 3D print is most likely not 100% watertight, it is good enough to make your GoPro float in water.

I designed it 3D-print friendly, but also with common engineering sense:
- no need for supports, the big inner overhang is sloped
- sharp edges are rounded: especially important in high stress areas
- also the edges sitting on the printbed are smoothened: they could cut your hand otherwise when tightening the cap
- walls are thick enough that some infill will be printed to get a sturdy part (two other prints I tried from the site where bendy, weak)
- yet tried to keep size to the minimum not to get a bulky part
- surface is grooved to create better grip
