this is so ghetto
but... i found these little rubber pads that were on the bottom of my old printer
...they keep it from sliding around. i took those little sticky pads out to the car and put them between the handle and the door (were toyota should have put some dampers! bastards!) and those keep the handle from vibrating against the door
so if you have a spare printer or just one that you dont care if it slodes around, just do what i did...that sheeit works!
