One Ring

Lighted OneRing. Attached is a Ring, and exterior shell that serves as a support structure for letters. Unfortunately, letters were messing up the exterior shell, and double layer shell would obscure the light too much. So I had to use the interior shell. But this way the letters are visible, and had to be infilled with UV Resin, and covered with gold paint that obscured the light somewhat, and made the whole thing look sloppy. Hopefully your printer or setting will allow you to print exterior shell undisturbed, and no post-print work would be necessary. Let me know if you are more successful than I was.
The ring is ⌀120mm, printed as one piece without supports (the shell (in or out) serves as support for letters). The cavity is small, so I used 3mm led strip with 10V power supply.
