Needed to use the 30 degree wedge for my installation, but wanted to also use the security cover design. I remixed the bottom mounting frame with so that it mounts 30 degrees offset.
I use 3mm heat inserts for the two small holes on the top, but you can use normal screws if you want.
If you need the bracket to be the other direction then just mirror it in the slicer.
Prints without supports for the 30 degree model. You may need supports on the 45, and likely will on the 60 and 90
Edit: I've added a 45, 60, and 90 degree versions as requested
The author remixed this model.
30/45/60/90 Degree wedge mount instead of direct forward facing mount
