Radome for Red Rocket LNB Dual Feed?

Adrian G4UVZ

Assuming that a way can be found to fit the plate feed to the Red Rocket LNB......maybe splitting the two elements in half and bolting together?
Has anyone considered '3D Printing' a Radome?  
Outside of my field of expertise ...not sure what the RF properties are of the various plastic filaments?   but the front window could be very thin?
