Where do you source your UV glue? I can't find it for a good price (except from China, but shipping is too long). So instead I combined what you and Rusty did:
I used Rusty's thingiverse STL, and 3D printed it. 0% infill, 2 shells, white PLA, and stopped the print before the top layer was printed. Ended up with an empty shell of the glow gasket without a top, which I filled with glow powder and put a layer of two-part epoxy over. This is result:
Glowtimes are probably better than GITD filament (heat degrades the GITD material), but probably not as good/dense as CRX's UV-glue-based gaskets. I say probably because there's no way for me to test it. But it seems like a good compromise between the two, especially cost-wise (at least for me).
