Fidget Nut Spinning Trapped Nut Toy

One of the first things I made to print on a 3D printer because it's something only a 3D printer can make.  The middle nut will spin after all the supports are removed.  I've uploaded the SolidWorks part files for this so you can edit as desired.  I was unable to upload the SolidWorks assembly file.  I typically print this in PLA with 1 or 2mm perimeters/top/bottom and 25% infill.

****IMPORTANT:  Print this upright (see slicer pic) so that only one end is on the print bed rather than both ends.  This is to enable complete removal of supports.  Printing on its side will cause supports to form in the threads on the middle nut that you won't be able to remove.

****ALSO IMPORTANT: When loading FIDGET NUT 1-Basic.3MF file into your slicer, make sure the components are merged into one part before turning the Fidget Nut upright.  That is to make sure the middle nut remains in the same position when being turned upright.  I don't know why but, Prusa slicer doesn't automatically make this 3MF file into one part with two components when I import it.  So, I have to merge the two components manually.  If you use file FIDGET NUT 1-Basic_Prusa.3MF you don't have to do the merge step.
