This is a redesign of just the nut. I have had some of these out in the field for 14 months now and what I have found is that no matter the glue I use the magnets always come loose. So I redesigned the nut to use 2 10mm x 2mm magnets internally with a friction fit keeper.
This is designed for printing in ABS since it seems hardier out in weather compared to PLA. Since abs does not use a part cooling fan there may be some slight sag. I have increased the dimensions of the magnet channel to compensate.Print with Threads facing up.
