T-Nut for 2020 extrusion M4 thread.

A simple T-Nut you can print for 2020 extrusion bars. More specifically, this was for my Neptune 4 Plus Rotating Reverse Bowden Cannon . I used PETG, have not tried PLA but honestly wouldn't. 0.2mm layer height I used 2 raft layers so that the threaded hole doesn't deform on the bed 3 walls, 3 top layers, 2 bottom layers Run an M4 screw all the way through the threads after printing before you use it or it'll be too tight. Running the M4 through it a couple of times really helps.
