CNC long nut box

I made this to hold a long M8 nut in order for my cnc to move properly using M8 threaded rods. It works great and holds the nut in place, to put the base inside the cap (although it isn't needed, it gives me more security) I used a vice. I used this model for my X and Y axis (Y axis was a little taller but it isn't a thing printing something to rise it.
