Nice, 3D printed side panel? 

I see layer lines and seam. I like the idea.

Radiator had to sit on the back side of the middle case plate, so I cut a larger hole that the rad in the back plate to be able to slide it on/off and then covered that with 3d prints bolted to the rad. Ideally I would've liked to have bolted it to the back plate but there isn't enough room on one side before the slide lock. It's 2 pieces.
