I will need at least two, probably four B&O CPLs for my layout and decided to give a crack at resin 3D printing them. Having a copy of the B&O standards, I originally tried everything "to scale" but as one might expect the effort was wasted. I thickened up some parts and tried some different supports and print orientation; Here's the progression:
I have come up with what I think is a presentable model (below). The signal heads/markers are separate pieces attached to the mast/ladder printed as one piece. I'm still making some modifications, one idea being to mold in a hollow core into which I will insert a straight steel wire for stiffness and to hold the mast straight. But that wire could also potentially serve as a ground for wiring up some LEDs into the signal head (which may be slightly crazy).
