I've just contacted the designer, if I credit him and put links to his design, I'm allowed to sell the frames as long as buyers agree to subscribe to his YouTube channel. I might do that (on a small scale) I think I'd enjoy that! I've got like 30 frames sitting doing nothing right now. But if you are based in the US, you might as well get them from his site as I will be selling them for the same price as it's a fair price.
BTW, ABS is both lighter and stronger than PLA, don't know about nylon weight but it might be overkill, as I've said I have been crashing the ABS one hundreds of times without breakage.
