I understand the intent, but feel that there are so many other loopholes that put much worse weapons on the street than a printer. Besides, my prints can barely sustain normal use, much less a bullet being fired from them. I would think that this is more of a risk to the person holding the gun than who it’s pointing at.
If you have the 3d model, you already have the drawings. Quite literally. Just need to print off some views with measurements, if you want it on paper, otherwise, use the CAD model and get measurements as needed.
At that point, it’s just down to having the tools, skills, and material. Someone with good skills, tools, and material could make the equivalent parts faster and of better quality than a bed-slinger. Someone without the skills… well, they’ll probably have time to build the skills in the process.
Now, when it comes to materials, I think that there’s definite risk there. Wood often exhibits worse shear strength along its grain than well-tuned printers do along layers (a good example of this weakness can be seen in the rear totes of old Stanley-Bailey bench planes - it is a minority of them that have not sheared where the handle meets the mounting section). So, that has to be taken into account in laying out the part in the raw material.
