Tom,
Cable tray cables did print - in fact, I have a scaled up version that may work a bit better. Haven't decided how to do these - the 3D printed cables or 0.20" dia. styrene rods, or old telephone copper wires.
My new LCD came in Thurs. so Fri. a.m. I overhauled the printer - replaced the FEP vat bottom (and 2 stripped machine screws in the vat gasket), and then the LCD. Only....that was NOT the problem with the holes in parts - one of the LED Lamp cubes was burned out - only saw this after closer inspection. So, good ole Tom F. has come to the rescue with the lamp fixture out of his now defunct Sonic Mini and it's winging it's way to the Mocksville Ship & Boat Yard.
In spite of this, I'm still printing, but only by carefully avoiding the area of the build platform that in is the area of the dead cube

So, I began revising the Mk. 37 FCD Friday and have run one print and will do a couple more tomorrow -
This edition revises the telescope ports, adds hinges to the operator hatches, and cleans up some small details in the exterior design -
The print today had a splintered stbd rangefinder arm, so another couple prints are in order. Doing these in Rapid Black and the detail is really exceptional.
Still working on stack yardarm installations - slow going with revisions along the way - all part of the development process.
