spikes, anti birds and cats

thingiverse

The purpose of this project is to stop unwanted visits from neighbors' cats that like to do their business on your outdoor space. To deter these unwanted guests, place a row of bird-spikes-like pieces along the edge of your balcony or patio railing. This ingenious solution prevents pesky animals from accessing the area without causing any harm. The spikes are cleverly designed so a curious cat can't find footing, but are spaced wide enough that they won't get their paws stuck. Best of all, these individual units can be connected to form one long strip that wraps around the perimeter of your outdoor space. Before installation, make sure to clean the surface and apply a small amount of silicone sealant as needed. If you're printing Bird_spikes_03.stl on a 3D printer, be aware it's been optimized for faster print times and uses less plastic than other models. Consider slowing down the initial layer speed and increasing the retract speed to get the best results.
