This is a PLA+ print I made last year. It is a vertical blocker for the gate porch.
The original one is too tight and makes opening too hard to lift.
Surprisingly, it holds up pretty well. It is exposed to heat and rain, also in our area, which has pretty high humidity, around 55-65%
Do you have any outdoor prints that lasted you this long?
I have quite a few printed things outdoors, some load bearing through summer and winter, for several years now. None have failed or shown any signs of fatigue or breakdown. The PLA SCARE about being outdoors was either over blown or filament has improved. Maybe both!
I remember printing with my Anet A8 back then, the PLA smelled sweeter than today’s PLA. Maybe we’re getting more additives to make it stronger 
I have a pla topper on effectively a fence post (clothsline) that has been there since 2016. It is showing some UV damage but it is in open sun exposed to NS weather every day. The PL premium that glued it on is in far worse shape. PLA needs very specific conditions to decompose generally it is industrial digester, compost systems. I tried in a house hold digester but it never really broke down at all.
When “they” say that PLA is biodegradable it doesn’t mean in a short time. It will degrade in about a hundred years, normal exposure outdoors, as opposed to ten thousand years for other plastics. Still sounds like a small win anyway.
