Designed this because I was not comfortable with the camera protrusion on my BV9800, would scratch it all on rough surfaces and not helpful when trying to use the gradienter from the toolbox app.
Also prevents from accidental button/fingerprint presses, found those to be quite annoying sometimes.
Short version needs some "persuasion" to fit the phone in if printed in something such as PLA, managed to get it in with some help of a air dryer.
The full version should add 1mm height to help protect the screen, maybe TPU would be better here, can't test as I have none around though.
