The file 'Large Bolt And Nut 3D Printer Model' is (stl) file type, size is 96.9KB.
I found this on Thingiverse and now can't find the original. The bolt and nut print twice the size shown in the picture but I reduced it down by 50% on my Davinci 3D printer.
This can be great for kids to play with or use it to build a screw in sensor mount if you hollow it out and place the sensor inside.
