I have a cheap/quick/dirty deer and rabbit fence around our vegetable garden. The doors are simple PVC squares with deer netting that used to attach to the fence via hooks at the top. This design turned out to be very fiddly. The new design seems much easier to manage - simply drop the door section into its slot.
This is ASA. I’ve had some PLA+ parts that have been outside for 7-8 years and are holding up really well. The old garden gate hooks were PETG and were still in pretty good shape after 3 full seasons and had to flex pretty often.
Granted, I live in SE MI so our sun isn’t super duper intense.
And totally agree, once you get in the mode of “I can print something to make this better” you start finding more and more things to make.
