My Tank Thread
Welcome to Reef2Reef.
To me, PMMA means polymethylmethacrylate. "Acrylic" aquariums are made from it, and it could be used for many other things.
Beyond that, I'm not sure what you are asking.

I think I finally figured out my process. PETG printed hollow cylinders open on the top. Put 1-2mm resin. 30-45 min later when resin is sticky enough to attach and pull away stringy from your finger, put in ceramic magnets, then fill rest of cylinder with fresh epoxy (old stuff will be too hard) and dry overnight. Then I can take those magnets and stick them into a frag rack, held in with super glue. The magnets hold, they can be monitored for rust (idk if ceramic rusts) , and the neodymium magnets will hold strong on the wet side!
I’ve also experimented with resin encased “dry side” magnets that can be submerged to hold frag racks on the back of fake AIO walls where the back of the wall is a wet chamber. Pretty excited about these, got real into it.
