I'll upload a new model before unfolding. I already added the shell injector, as well as smoothing out that section of the gun (it really needed it), as well as adding the power button type things on the slide. I wasn't sure about the flashlight, but I'll go ahead and do it now.
For the ribs, I could do that, but would you like it better if the ribs were integrated into the gun? I could adjust the unfolding so that if you don't want the ribs, just don't print the last page. I think trying to make the ribs floating face indents would lead to a lot of problems and warping.
