Apex Micro Arm Bumpers

I made these arm protectors for my ImpulseRC Apex Micro quad. Weighing in at just 0.4gm each, they use 2 motor screws to mount, leaving 2 "good screws" contacting CF directly to hold your motor solid. The A and B files are just mirror images of each other. Print a pair of each for a symmetrical look, or 4 of the same for a different look. No rotation necessary, supports are required.
