Bird strike/hit prevention tool

This is a tool used for painting dots that prevent birds from running into windows. Over 1 billion birds run into windows every year worldwide but many solutions to this cost a whole lot so this is a DIY sustainable solution to that problem. The dots are 2.125 inches apart, this design is based off of 'Solar Gard Saint-Gobain WingSafe™ Black Dot'. The idea is that the birds see the dots and dont think they can fly through.

What youll need:
-a stage 1 and stage 2 file printed
-paint or a paint marker (still figuring out which kind is best and theres such thing as glass paint but any outdoor paint should work)
-a level (optional but encouraged)
-a ladder can be helpful

Instructions:
-clean and prep the window making sure its decently dry
-print the stage 1 tool (there are two versions of everything right now, one that can be used with 3d printed screws or the version you can use with a rubber band, ill be making a version with neither soon.)
-print the stage 2
-strap a level onto the
