Bird defense

Besides the fact that we love animals, birds can make a big mess at our places. I had to cover a lot at the entrance of our apartment, to prevent daily cleaning. The prices for bird defense are pretty high. Let's print it!I recommend PETG for this project. PLA could maybe not resist the UV and heat/cold. Check your filament individually.Because the print is very thin, the heatbed should be hot and with some adhesive.-Each row is about 20 cm long and has a width of 2 cm. The height is 4.5 cm. It has multiple holes to screw it somewhere. Between the cones are 1.5 cm gaps.
