That is truly nice that you would do that. 3D printing comes in many flavors, including metal. I always thought it was rather expensive, and setting up the program would be time consuming. I admit to not knowing much about it, but am pleasantly surprised to find that neither of those things are true, at least for plastic printing.
But if you have a phone # for Cattail in Lancaster County, maybe they can do for me a couple of sides that have been sitting at an amateur foundry in that vicinity for two years. Same foundry that had my Erie-Built sides cast in bronze - but I think he sort of lost interest.
Most of the stuff I have done is lost wax or lost plastic. Forumites will remember I have nickel silver and bronze PAs, done by putting MTH bodies in plaster and subjecting them to intense heat, followed by injecting very hot metal. Stevenson Preservation has a line of fully clevised side rods done with my patterns.
