ZMR250 Beefy Long LED Bumper Set MKII

A set of beefier led bumper for the ZMR 250 quadcopter frame for use with 7mm arm spacers.

After designing the beefy led bumper kit MK1; I noticed the front bumper was the flimsy one now, so I redesigned it to last this time.

I also added indentations in the screw holes to fit the screw head, this way you have four less screws to unscrew when unscrewing all the screws in the bottom plate.
