The printed pieces went together pretty well. The bolts are still a little loose so I'm hoping the seam lines are a little less noticeable when everything is tightened up. (I think I'm getting a little carried away with the Adobe "remove background feature",  or maybe I just don't want anyone to see my messy work area. ;-)

I'm happy with everything except maybe for the black frame that holds the display in place. For sure the tabs used to bolt the pieces together are too flimsy. I managed to break one doing the assembly. As you can see the display fits in quite snugly. I am still waiting for the gel filters that will sit between the display and the blue screen mask to hide the display outline. Right now the four metal tabs with screw holes (on the display) are the only thing keeping the display from falling through to the back. The screw holes are pretty small plus I don't want screw heads sticking up as ideally the display should be pressed directly against the filter to prevent the image from being distorted.  So for my own piece of mind I will be adding some supports on the back of the frame to hold the display in more securely. I will also probably use some black electrical tape to the front edges of the display to keep it in place and to help blend the frame in with the background better. Here is the updated frame model.

Original on the left, and on the right a model with stronger tabs and some platforms at the corners of the opening for the display panel to rest on. Rather than reprinting mine I will live with the tabs as they are and glue on some corner supports that I will print separately.
