Spike Pigeon Deterrent

Summer has arrived on my balcony, but it seems to have brought along some unwelcome guests.Now, there are several pigeons perched on my air conditioner, causing quite a mess with their droppings. Despite shooing them away multiple times, they stubbornly return, so my only option is to install a deterrent to keep them from landing and nesting.I first searched online stores and then Maker communities on social media, but as usual, I couldn't find anything that suited my needs. So, once again, I went with "if you want something done right, do it yourself," and in just a few minutes, I came up with the first prototype of my "spike pigeon deterrent." and with the second prototype, I reduced the weight to 37 grams.I printed about ten of these and screwed them onto a piece of plywood I found in the garage.For now, it seems to be working as a deterrent, and the balcony is clean again.
