3D printing with the "hot melt glue gun" approach currently has some limitations. It is not always light tight or water tight for one. Easily fixed with a little silicone or body putty. The other more serious one for me is that it tends to be somewhat weak across the "grain"....at least with ABS. Also, expect a little sanding when there are tight fits. There are other 3D technologies out there that are better (and I use almost daily!), but not quite ready for home use but will be in the next few years. That said, if you are careful with build direction and are willing to fill it a bit if needed, you can make a lot of stuff with it including cameras. I personally have a hankerin' to build a CNC router and start making large format cameras among other things! Maybe when I retire.
