Grappling hook arrowhead

Its a grappling hook arrowhead bases of off Hawkeye and Green Arrow

Use 1.75 mm filament for the hinge

Adding a spring for the piston isn't necessary but it will make resetting the arrowhead easier

In order to make sure the screw fit I printed it with a 0.2 mm nozzle, if you don't have that you could print it with a 0.4 nozzle but you should adjust the z seam settings as they generally mess with the threads. Also printing it horizontally with supports helps.

If your slicer allows for different infill at different parts of the build I would recommend 100% infill for the screw and base area.
