I want to express my thanks for their efforts in creating pulleys and spools for my Open Hearth furnace doors. Per my understanding, Ray made the drawings and Rod did the actual 3-D printing. 
I think these came out beautifully.
Below is a photo of the unpainted items along with a Plastruct M2 motor.
In this next photo I have test-fitted them in place. They have yet to be painted or accurately positioned, but you get the idea of what they are supposed to do.
So, again my deepest thanks for Rod's and Ray's help.
And by the way, Ray 3-D printed those doors and door frames for me, too!
George
