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.

Nice work!
One of the interesting things about modeling and then printing replacement parts is figuring out which features matter (like shaft diameters and spacing in this design) and which you can take some liberties with to make printing easier. For example, for the part on the left you may have been able to add tapered feature to the rod insider to let you print the part standing on the flat bit on the far left without any supports. Another possibility might be trying to get the part to lie lengthwise by modifying the cylinder some as arced parts have deceivingly big overhangs. Perhaps you could give it a small flat spot.
