RE: Exo Terra build questions and comments
I'm trying to remember my build but, I can't recall if I experienced the same problems you're having. Idid notice that about half way through the build the parts didn't seem come out of the bags in order. Measure all the screws as you install them to ensure you're using the correct ones.
I think I remember having to open a back early to find the parts I needed. In the end, all the parts and hardware were accounted for and I wasn't missing anything. You'll end up with a lot of accessory pieces and extra toe block/arm mounts.
Also, have you figured out what those two panels that are textured on one and seem to fit together as if they were supposed to hinge on each other? I can't find it in the guide and don't see a practical use for them.
