The file 'Captured Nut Fidget Toy – Customizable 3D Printer Model' is (stl,scad) file type, size is 8.9MB.
I love little spinning fidgets, and I couldn't find one that had the zip and spin that I really wanted, so I made this little print-in-place nut-and-bolt twirly fidget.
The gaps are all 0.4mm and the overhangs are 45 degrees, so make sure whatever printer/material/settings you are using can handle that, or you'll end up with an art piece about seized bolts instead.
Update: Added an extra long bolt with slower drop/faster spin. (You will probably need a brim or something when printing the long one.) Added openscad source.
