Migrated to: https://www.printables.com/model/545010-rocket-horizon-and-standard-camera-mounts-for-este I created these mounts to provide a single solid semipermanent attachment to an airframe for an Estes Astrocam Universal. I didn't like the sort of taped affair that came with the camera. With the 40 degree mount and a front-surface mirror (17mm x 14mm, approximately), you can view the rocket's flight looking toward the horizon. You can see a sample video here: https://youtu.be/WhhW3ay8_go There's a hole in the cap, so you can drill the plastic cover for the USB camera and see the camera's blue status LED without taking everything apart.
