screwing fidget toy

i love to fidget with stuff so i made this little thing that i can twist and turn

i ahve no clearence designed into the model so if you want that you can jsut scape the nut bigger then the body i pritned the body at 50% scaling and the nuts at 50% but 52% for the nut also worked,

protip if ur having issues with strining and the nut not coming on i jsut heated the thread parts with a flame until they were soft but NOT MELTING and hten i threaded them onto the screw and jsut kept turnign until they ahd cooled down
