This is a worm bin made to feed worms to make better garden soil in garden beds for flowers or vegetables, I have tested it outdoors for over a year now in ground and had it sat outside for a few months now and it has held up fine being made out of white PLA. 

Burry it up to the lid in a garden bed and throw in any food scraps like eggshells, fruit/vegetable scraps, teabags and used coffee grounds.  

I printed this with 5 percent infill with pretty much standard settings on everything else, no supports.  

PLA is always simple to use and will last a good amount of time whoever, PLA degrades over time due to outside conditions like the sun and rain so using ASA is recommended for much longer lasting and safer product (less degrading means less micro plastics).
