I like to fly in small spaces, and found the 30 degree camera tilt to be a little too aggressive. This is a modification of the official happymodel files. Just like the original, it will fit the 14x14mm Caddx EOS2 as well as the stock camera just fine.
Note the mesh isn't perfect and has some small defects, but Cura handled it without issues and you can't notice model defects once printed.
Print TPU slowly (I used 10mm/s for my bowden extruder). Supports are not strictly needed, but using them will improve print quality around the snout area.
UPDATE: I've included another file which has a holder for an UXII/AXII circular polarised antenna.
