I created these for a friend who wanted to replace several of her patio lanterns that were being destroyed by sunlight. Apparently they are hard to get and expensive on Ebay. I have no idea how PLA stands up to long term sun exposure... but they feel like they'd last for quite awhile as they are less flimsy than some of the commercial ones I've seen. I printed this with 6% infill, no support or raft. There were a few strands of plastic in the middle, but I just pulled/cut them out.
