Crane Hook

This is the model of a strong hook that I have printed and used for a crane project. It requires 2xM3 Bolts, 4xM3 Washers(not required do help), 2x M3 nuts. You could also potentially use some nails which you flatten the end off of once they are inserted or even print some bolts and nuts if you do not have the required hardware. Hope it is useful.
