Both bits could easily be moulded. I would suggest you try some epoxy putty, but failing that plaster, Fimo or even paper clay (made of toilet paper and white glue, check out google). I would remove the little ball on the top, since it can easily be replaced later. then press the top, pointy end first into plasticine (for moulding paperclay) or epoxy putty and allow to set. When you pull out the piece you should have a simple mould that you can then press more epoxy putty into. The same process for the bottom.
If you want to get more sophisticated something like Composimold is a reusable moulding material that you can press epoxy putty into to make small parts.
I expect somebody will come up with something easier but these ideas are not complex.
