There's about 0.8mm of clearance between the bracket and the remote. You could take this down a bit to get a more secure/friction fit. The hole on the bottom is not entirely necessary and only intended to make it easier to remove. If I print it again I'd make I'd make it a much smaller for aesthetics. The rails on the back allow 2.5mm clearance for a pan head screw
