R36 Max Console Handgrip

This is my first 3D print design that I merged together with a handgrip/controller 3d print. It does have quite a few issues since some of the pieces don't touch in the back and I have no easy solution with my experience.If you find an easy was to merge my model and perfect it on your own, do so. I made the box where the console goes pretty tight and so there is maybe about 1mm of sway.
