I made these initially as a joke and they turned out rather well so here they are.
There are 2 types of nozzle one with the end closed which I used for the lights so you don't get a beam of unfiltered light shining through and one with the end opened which I used for the bauble.
All the examples were printed on the Elegoo Mars.
For the lights I used translucent resins which I then varnished using clear gloss acrylic to create a glassy look. the lights were a set of micro battery powered LEDs. I suggest you print a smaple light shade and test for fittings with any LEDs you might use. The cap was printed in black. The tolerances are pretty tight, so again I suggest testing (you may want to increase scale on X and Y if you have some issues). Lights were fitted using a hot glue gun.
The bauble used an opaque filament which I then primed and covered with gold leaf Rub n Buff and sealed with clear gloss acrylic. The jewels are 3mm crystals which should just push into place. There is a cap with a hook on it that will suit the bauble better.
These should print well on and FDM printer too but you may need to tweak the threads..
