WLToys A959, A959b, etc. bumber.

Designed as a sacrifice part to save the front (or rear!) wheels and suspension system. The bumper has an angle to make the car jump over smaller obstacles. I did not test with PLA but as it is made to be destroyed and or deformed to protect your car the brittleness of PLA may be good. Tested with PETG and ABS. Still too fragile and breaks too easily (but saved the car!!! :D ) Caligandalf tested with TPU and workes perfectly! So I highly recommend to use some flexible filaments like TPU or high strength and better ductility like Nylon or PP should work better than the traditional ABS/PLA/PTG.
