DISCLAIMER: I will not be held responsible for any damage done with this model.
When I started this project, it was really just one of those things to see if it could be done. I did not use Rio's personal models; Instead I used his drawings and made my own. Internally, the gun doesn't function. The trigger doesn't even move. Externally, the model is completely accurate with the exception of the slide stop. The only moving parts are the safety lock, hammer, slide and barrel. I also had to change a few dimensions due to the 3D printer tolerance so if CNC'd; it may not work together as well. If you plan to 3D print it, then you will most likely have to use your own. I know that some companies that function like Shapeways are cracking down on the dangers of printing functioning firearms and may not allow you to print this file. If you do have the ability to print this, I Highly recommend using bright colors for the barrel or even the entire gun. While no laws in the US prohibit having this model on your persons, there are multiple instances of people (especially children) being shot by police for waving around fake realistic weapons. For those of you who think they cannot handle the responsibility or plan on giving this to someone who cannot handle it or just have no need for a complicated replica, I have supplied a slide without a moving barrel.
For reference, this was printed on a Dimension BST 1200es. I edited the dimensions specific for this type of modeling. No sanding is required on any of the pieces. I will be unable to complete the model the way I would like so the files I have completed are now available.
