Nut for Newscrew

I needed a nut to put on the screw.  In Blender I used a boolean tool on a cylinder with the screw. Then I enlarged the cylinder a little and send it to the printer.

It took 1:49 hour to print it. It is 2 cm height and 4 cm wide.  Would it have been better if I had adjusted the proportions of the initial cylinder to the same as I had for the screw?  That is something to test...
But the nut works.  I had to twist it for a couple of minutes back and forth to make it fit smoothly.

If you want to create a copy of this screw and you have access to a 3D printer then you can download the file at Thingiverse or from YouMagine.
