Designed to take an LED tealight this low poly ball also has adapters for the submersible lights which are much brighter and come in different colours. For some reason the ones at lights for fun come in 2 shapes so 2 adapters supplied :)

No support is required as there is an internal support built into the model that just twists off when printed. There are also a couple of strut supports to stop the inward bit from slipping when printing. These can be scalpeled off if you like.

Print at 0.3mm layer height for a more rustic/taffeta feel, otherwise 0.2mm gets a better shell.
