I wanted to record a print and could not becuase the current mount I have does not allow for access to the charge port. After weighing my options on purchasing one for $30 I decided to take a few minutes and create one myself and voila. I am continuing to refine the file but this current file gets the job done for now. the dimensions of the gopro hero 2 are almost identical to the custom mount so the first use plays for a pretty tight squeeze, but after several switchouts the abs plastic moulded quite well and the camera can be easily placed or removed. Print takes approx 2 hours depending on your build settings and printer.
