I really like the Glowing Ghosts Spooky Ghost, but wanted the tea light to fit snugly so that when my kids moved the ghost, the tea lights followed it.

This locks the tea lights I purchased snugly into the plug. The plug then has a friction fit with the original Spooky Ghost that wont fall out when lifted. It is also easy to remove by gripping the tapered edge and pulling down. There is a cutout on the bottom so that you can turn the tea lights on and off.

The diameter of these tea lights is 36.5mm. Anything smaller would technically fit, albeit, loosely. YMMV on any tea light other than the ones I linked.

The print is only 3.5g and took 7.5 mins to print on my Bambu Lab X1C.
