Parametric cat & bird spikes

thingiverse

Spikes to scare away cats and birds from window sill etc. It's a parametric project - you can customize size and height, number and height of spikes. There is an optional arm (holder) to be mounted or placed under the pot (set holder to false) The uploaded stl is 125mm x 68mm x 15mm. You can download .scad file and open it in Open SCAD. Just customize variables, press F5 to see changes, F6 to render and export to stl. You can even print an animal safe version - with spikes truncated. My cat (and my neighbour's one) never sit on my window again, don't drop pots and don't destroy the side walls when they go down (they moved to another window where they are allowed to sit)
