General purpose hook

General purpose hook that borrows from the strength of the screw with the trade off that you'll need a longer screw than you would normally use. Shaft of the screw should be 4 to 4.5mm in diameter. Plug included to hide the screw head. Recommend a 4*50 screw (9 x 2") which is a common screw size in the UK. If using a power tool for the screw note low torque will be needed.

Alternatively if you print two and stand them side by side you can use them for robot legs.

Updated: added a rounded version that is more pleasing to the eye.
