This is a very simple mount for a GoPro to be mounted on top of the battery without a hull. You'll definitely see the rotors in the GoPro's image frame with this mount.Designed in TinkerCAD...my first attempt at something with it. https://tinkercad.com/p/acc03ee505b39b50/51You can see some different iterations in the photos to the left.Here's a video of the mount in use: http://www.flickr.com/photos/retrocactus/6674996425/in/photostreamPrint 2 of these. I printed mine at 25% infill, 0 shells on a Thing-O-Matic with a HBP & a Mk6. The bridging (for the velcro passthru) doesn't have to be perfect for it to work, it just helps. Mine turned out pretty decentFeed each one through the velcro for the battery. You'll need to flip the battery around so that it connects with the wires up and toward the back of the GoPro.Optionally, use a ziptie or an elastic band to further secure the GoPro if it's loose.Don't forget to flat trim the Drone before your first flight to adjust for the weight!
