About this 3D model

This is an easy print, and what I understand to be one of the harder parts to source otherwise. I've got more in the works. These are converted from sketchup models provided me by a friend, I didn't model them. That said, converting them from sketchup, fixing the results and scaling, well, it's a lot of work. EDIT: I've just added the military knob too. It's not as detailed as I'd like, so I don't know if it will work for you all. But here it is anyway. So, I hope this helps some of you with your builds. Enjoy.
