Ballnut with captive steel M5 nut for Articulating Raspberry Pi Camera mount

I built a camera arm using the M5 thumbscrews from @Zach, and the ballnut with M5 nut inserts from both @darkcoffee and @bulbasaur0, but had issues with the steel nut not staying in place when the camera head was adjusted. This model provides a stronger base.

This model accepts the M5 nut plug to create a captive nut insert for better strength while adjusting the camera head.

Insert nut into plug, apply superglue or CA to the inside of the ballnut, and insert plug into base of ballnut. You may need to play with XY size compensation to get a tight fit. You should need force to insert the plug.

No supports needed, but may be beneficial on the ballnut underside.
