These two models are covers / protectors for the ProDrone.pl Pro Cloverleaf FPV antennas : the only difference is that the four lobe one is a little bigger. You will have to print two times the same model and then assemble both halves together, using glue or plastic welding, or even tape. These models were designed in FreeCAD, feel free to ask for the fcstd file if you want to edit it.
