Perspex joiner clip

I needed a small sun box to start my seedlings growing, and to keep birds away. I had some small sheets of clear Perspex.All I had to do was work out a way to join them, so I designed these clips. The air can still circulate through it but the birds can not get to the plants. Just lift the whole thing up to water.To assemble you need some Perspex 3mm thick, 5 pieces cut to your own required size. I have tried printing the clips in PLA,PLA-CF,PETG-HF.I would use some glue on the clips once you are happy with the Boxes size and shape.
