thingiverse
A YouTube video showcases two nuts threading in opposite directions on a single bolt, inspiring Thingiverse user msruggles to create his own "Screwy Screw" design. The original STL files are available for download, with users encouraged to attempt solving the trick before viewing solutions. To recreate this illusion, choose between small or long bolts and build both nuts following specific thread directions. The nuts and bolt have unique sinusoidal profiles and varying thread starts, providing a challenge for 3D printer enthusiasts.
