Suspiciously Evil Caltrops

thingiverse

Caltrops! A caltrop is an area denial device consisting of two or more sharp spikes arranged in a specific pattern, guaranteeing that at least one spike always points upwards from its stable foundation. The tetrahedron shape is just one example. A plastic printed caltrop may not be extremely hazardous, but it can still cause injury! When printing, exercise caution - use them only as props or decorations to avoid any potential harm. https://en.wikipedia.org/wiki/Caltrop
