I've done some projects like that, although not with as many parts! I think the main disappointment that awaits the author is that within two years or so, the epoxy will turn yellow. These resins are unfortunately not UV-stable, even if kept in a reasonably well-lit area indoors (bookshelf, etc).

There are resins you can use for projects like that if you want them to last, but they're less fun to work with.

Would putting some UV filter glass, the kind often used in museums, work to protect it the resin? I'm wondering if you fixed a glass casing around it that way... granted you'd have corner seems for the glass though

Maybe a cylindrical glass instead?

I tried that. Refraction makes it hard to understand what you're even looking at. https://fellerts.no/img/epoch/first-cast.jpg

I was thinking about a larger with less curvature glass. It might also be interesting to see if it's possible to match the refractive indexes of the epoxy and the glass.
