I've got the OEM LG Bumper Frame.
You'd think it'd be raised enough to keep the camera lens from touching,but,noooooooooo.
If you find one,lemme know.

 

I bought these cases from Amazon. Criteria was to have a raised surface to protect the camera lens and screen, with a lip, and be clear to showcase its design. Easily removable without scratching to swap batteries.

I am looking for one without a back. Just the frame. Something like a TPU case. Has anyone seen one. I have had one for my last three phones, but cannot find one for this phone. Seems strange

 

Not exactly what you're looking for,but,here's this:
(many listings on e-Bay & Amazon,Google search OEM LG V10 BUMPER):

It's a hybrid metal-coated plastic/TPU backless bumper.
I have it myself & went as far as separating the two pieces,to see if the TPU would be rigid enough to stay on & it's not,you need both pieces.
It's pressed together,so,you shouldn't have to worry about it separating.
Just take care in removal/installing,as installing it backwards or,upside down will likely have the outer piece break on you (did it myself,all in the name of science ,easily fixed w/a couple dabs of Crazy Glue)

 

Would you say its only purpose is to protect the aluminium sides of the handset? If so, comments?

 

That's pretty much it & when placed face-down raises it just enough to keep from touching the surface.
Not really enough to keep the backside raised in the same scenario.

 

I bought this case for $60... and it comes with a 9000mAh battery too! =)

Yes, I like it, but do note it doubles the "thickness" of the phone.
