GoPro Hero 3/4 TPU Bumper

This is a GoPro bumper for the GoPro Hero 3 and 4. The file GoPro_Bumper_V2.stl has a little hole for the top led and a cutout for the usb plug. Furthermore it's thinner, lighter and easer to pull over the GoPro than the design GoPro_Bumper.stl.
The last two images are of the GoPro_Bumper.stl.
