Quoted from mbwalker:Time to upgrade the 4" speakers in the backbox. Decided to keep the short speaker screws in place and at the same time make an offset plate with the 3D printer since the tweeter sticks out a bit. Still tweaking everything, so haven't installed yet.

I would suggest that you move the position of the 4 raised mounting points that the speaker is using. As it is, the factory speaker plate has the speakers mounted in a diamond position, with only a mounting stud at the top and bottom of the speaker hole. As your 3d printed spacer is now....the speaker is going to be mounted off kilter. It is not going to be mounted straight (in a squared off position) and it is not going to be mounted in a straight diamond orientation. It is going to be....."off", mounted somewhere just a bit away from a diamond position.
If you moved (rotated on the round spacer) the 4 raised mounting positions (that the speaker will be using) to be halfway between the mounting holes that are meant for the speaker plates.....it would make it so the speaker can be positioned in the traditional squared up orientation.
Unless you need the speaker mounting holes close to the speaker plate mounting holes (for strength or some other reason), I would think having the speaker aligned in a straight position when mounted would be the way to go. I think this would help visually anyway...if a person chose to not use the speaker foam.
Just my 2 cents,
