prusa i3 z nut adapter

adapter nut for z axis, allow you to use a 5mm thread bar
this is for those who don´t want to spend the money for a T8 lead screw
this nut fits the prusa i3 original parts, I made this design because I was making a 3d printer from scratch and did not have a T8 lead screw or nut for it, so this will replace that,
it fits a 5mm nut and is for a 5mm thread rod

any tips will be much appreciated, but not necesary,
