Thanks to @Pbourgui_1129854 for the original.

This is a release knob for the “cross” style release screws on specifically the Harbor Freight 8 ton long ram air over hydraulic jack but may be used on others as well. 

It fits nice and tight so as to not lose it. 

I like solid parts, so this is printed with 4 perimeters 4 top and 4 bottom layers with 25% infill, a 0.6mm nozzle and 0.3 layer height. Its not that much more to print in 100% which I have done with many prints that need to last years but did not think it was needed here.
