Creating bird spikes with 3D pen
In my first attempts at creating bird spikes, I simply used a quarter round or half round piece of old molding. Using a 16th inch drill bit I drilled numerous holes and then used the 3-D pen to partly fill the hole with extrusion from the pen and then moving outward creating spikes.
Although the finished product did not give me the rigidity in the spikes that I wanted it still seemed to work.
The spikes do not harm the bird as they are not sharp enough or stiff enough to do so. They end up being more like the bristles on a soft broom and more of an obstacle that the bird can't quite figure out how to get around.
A piece of styrofoam could be used in place of the wood, making it light enough to be stuck to a wall with poster putty. This might work great with woodpeckers and flickers that tend to roost on the sidewalls or under eaves .
Note: The Styrofoam will melt some with the 3D pen, so use gloves and some caution when working with it.
