Bird spikes

Bird spikes to prevent from birds' perching or roosting. It consists of two parts, two spikes and its holders. The holder has two holes so that two spikes can be placed through them.

This holders were designed to match frames of an outdoor unit of my air-conditioner. By modification of the holders, you can use for anywhere.

Drop comments for addition of other types of holder you want. For example, holder for rounded pipe or other shapes. Updates can be done by in python script easily.
