Fence stake protective cap

My son had the idea to place a "figurehead" on the fence stakes of the double rod mat fence. Therefore I had to design a new fence stake protective cap. It is based on the original and fits tightly on it. The OpenSCAD code is a little bit fiddled together, but it works and can be adapted if necessary, which I will do if I need to. The owls are from the SD card that Anycubic supplied with the I3M. I will glue them to the protective cap and screw them on additionally. Let's see how long PLA lasts
