This is a custom rig to secure a little key-chain 720p video camera (recording to MicroSD) to the body of a hobby rocket. The current model should fit a 34mm diameter hobby rocket that uses E class engines. I originally downloaded a model of the standard Key-chain 720p video camera from Thingiverse last year but forget who to credit. I used that model as a hole to create this one. This has been printed with an UP! printer in ABS plastic. I found I needed to cut away a little bit of the upper portion of the camera cavity - the bit under the sloped hood - for my particular model of camera to fit; you may need to enlarge this area before printing.
