So I completely modeled the LinQ quick attachment from scratch, my previous model was a remix from someone, it had rather loose tolerances and I didn't have the source files so couldn't really fix or do much with it. Now I have full control, I am also trying to find a way to print it with the bolt and nut inside the body already, so you would not need any bolt etc, that would be awesome. Thank everyone for the boosts on the old model, I really recommend you print this in the future though.
