This is a case for the GoPro Hero HD Camera. I printed this in soft PLA material. It was designed to be mounted on a R/C model airplane. The ribs on the front side are for shock absorbing in case of a crash. There are openings for the knobs and for the direct A/V-Out. Like this it is possible to use it as FPV camera.--> FPV: First Person View; more info on: http://en.wikipedia.org/wiki/First_Person_ViewPS: There are two files - the case and a GoPro model. you might want to use the GoPro model eventually if you have your own plans with the GoPro and if you're fed up in first use calipers to measure yours or to print it out and test fit before you buy it. I think it should be modeled quite accurate.
