Just 3D print it normally:
After, insert the bolt to reinforce it.

The author remixed this model.
I had issues with the original screw (ended up breaking it by accident), so I though I could model a version of it with the possibility of having a metal core, which would make it stronger.
So I reduced its size and added a hole to allow for insertion of a 40mm M3 Allen bolt.
