fill the thing with Lucite
I saw the same kind of thing on a McDonald's table near Quantico.
The molding holds the resin while it is being poured.
The pouring can be a PITA to get nice and bubble free though.

A coworker's hardhat, for instance, is an excellent place to test your epoxy pouring skills. Or so I've heard.It's not so difficult as you imply. Pretty easy, in fact, to get them to look nice and bubble free. There are plenty of youtube videos on this, for people who haven't done it before, and it's simple enough to do a practice pour on something small to try it out first, then utilize the lessons learned on the real deal.
Kinda fun, actually.

Depends a lot on what objects you re trying to embed.
Anything that can trap air is a PITA.
