Repairing Earmold Grabber

I have Oticon silicone earmolds. The little ball on the end of the left grabber came off yesterday, leaving a stub I can grip but not as easily as before. I want to try to build up the material and would appreciate any thoughts on appropriate materials to make a new ball like the right one. Options I have on hand are:

• Hot glue
• Other household glues
• Woodwind pad adhesive pellets – these are small pellets of adhesive that can be easily melted to glue pads into woodwind instrument keys. They would be a perfect material in that they set hard on cooling and are easy to work with, but the ones I have are a dark amber color rather than clear.
• Any other thoughts?

Thanks for the suggestions, Dusty. I don’t have ready access to a 3D printer, so I tried a couple of different dipping materials as you suggested. I made test subjects cut from a pool cleaning brush, slightly melted the tips of the brush fibers to add an anchor point, and dipped the tips in (from left) hot glue, a melted pad adhesive pellet mentioned above, and Gorilla brand super glue gel. The fourth strand is a melted but undipped fiber for comparison.

I found the hot glue to be harder to work with because it gets stringy very quickly. The adhesive pellet worked better but the color made me think it would look like an ear booger. The super glue won the test in my mind, so I started dipping. I don’t have accelerator so I just waited much longer than I’d anticipated for it to cure. This shows the super glue ball on the right of the picture and a factory ball on the left. I liked it well enough to proceed with another coat, which is now curing, and I went ahead and coated the factory ball on the other mold to make a matching pair and hopefully avoid having that one fall off in my hand. Thanks for pointing me in the right direction.
