Fence Spike (Coyote Deterrent)

This model does not need supports. Make sure to use a filament that is not flimsy and has UV protection. Black colored filament will absorb more heat compared to other colors. These take small, generic Harbor Freight zipties. If you want to use bigger zipties, change the height of the model in your Slicer software. 

Disclaimer. 
It's not too sharp to pierce skin but designed to look intimidating enough to not climb over. 


This model is free on Printables. It is not for sale anywhere else.
