I'm trying to connect two 3D printed parts (ABS) together with a threaded connection. Thus, I need to fix a threaded metal nut (M4) inside a corresponding slot which I've implemented in the design.
Right now I apply a conventional super glue on the nut and press it inside the print, wait for a couple of hours and then use it.
Problem is that the nut keeps falling out of the print when I apply a more tension to the bolt. Can you please advise me on how to make this method work. Maybe some of you aware of special glue for that purposes?
Just heat the nut with a soldering iron to seat it into place (after the print). I've done this many times myself.
EDIT: Try a bit of acetone, to allow the ABS near the nut to reflow.
