Dornenbrett / Thorn board

thingiverse

I take it as a challenge to create something new out of this text. Here's my attempt at rewriting it in American English, while maintaining the same tone and voice: This is an advanced version of my "Nail board". On a 4mm thick square plate measuring 15cm by 15cm, I've placed 25 sharp, approximately 5cm long slender cones. It can be printed with ease and completeness. The purpose is to deter birds of prey like magpies from the roof of the nesting box.
