/diy/ - Do It Yourself

I have a greenhouse kit that uses 2x2 lumber and plastic angle pieces. They attach to the ends of the 2x2s and have about a 120-degree angle to them. Think EZFrame knockoff. The whole greenhouse is 6x6x6 feet, so not large. A storm came through and blew the thing over. This damaged many of the plastic bits. I'd like to replace them with plywood gussets but I don't know how big I need to make them. They won't be supporting much weight as the thing is just covered in plastic sheeting but will have to stand up to wind. Any thoughts?
