Suncast Easybolt with a 14mm head (long version)

I downloaded some 3D printable hooks and went in search of a longer screw to replace the original Easybolt which is short and uses a 3/8 SAE hex screw. I found the Suncast Easybolt by @Terrywood02 on printables, which came with a longer bolt but requires a 7mm hex (Allen) wrench to tighten it in place. I tried it and stripped the head in about 3 nanoseconds. I then remixed it using a 14mm hex head, suitable for use with a regular socket wrench. This allows some reasonable torque to secure the part to the shed without the risk of stripping the head.

I've included the FreeCad file in case you want a different head size.

I'd recommend printing the screw with at least 50% infill, and in a horizontal orientation to make the layer lines perpendicular to the axis of torque. Make sure to turn on support.
