Bumper Spike

A Truck Bumped into my Bumper the other day so i made this simple but intimidating spike to ward off future tailgaters. It is designed to crumple and not do any real damage but only appear menacing I would recommend making out of PLA so if you do get in an accident it is biodegradable. ALSO check the laws in your area to make sure that it is LEGAL before putting a series of these on your car!
