If you've built one of Daniel Norees amazing OpenRC Formula 1 cars, you'll probably have broken a few front spoilers while you were testing it. The original front spoiler looks amazing, but it's a bit delicate and breaks easily.
That's why I have designed this "Hammerhead Training Bumper", which when printed in flexible filament like NinjaFlex, will probably save you lots of time, effort and filament making new front spoilers after crashes.

Make this using a flexible filament like NinjaFlex, using whatever infill you like. More infill is generally better as it makes the bumper more stable and able to withstand bigger crashes. No supports are rafts are required, in fact it's a very quick and easy print.
I designed this using OpenSCAD
