Nikon vintage camera

I edited this file so I could print it for my son. The original is not one solid body, so did not print well for me. I tied the lense together with the body so it could be printed. This is the last of a number of edits I made, it should print fine. I printed the last version for my son, please post if you print this so I can make any needed changes.
The one in the picture is printed with fuzzy skin in cura, will be smooth without it.
