First off, I have no grasp whatsoever of what goes into 3D design, CAD design, or 3D printing so please bear with me if this is a silly question…
Apparently, the only way to get hold of a tell tale activator for FastTrack is to purchase a new bobbing car of some form that includes the modified activator. Lionel does not sell the FastTrack activators separately and that means those of us who want to install tell tale activators on FastTrack either have to buy a new car we don't need to want, or modify an activator made for tubular track (which may or may not work on FastTrack).
So the question is, is it feasible, reasonable for someone to make a design for 3D printing for a FastTrack tell tale activator? My guess is, it would only have to be the activator and base, since one could use their existing posts and tell tale arms. I'm also asking because I think the FastTrack activator has metal plate or rod, which obviously might make a 3D printed repro more difficult (hard to tell looking at the poorly xeroxed and scanned instruction sheet on the Lionel site). And, would doing so violate any patents?
With all that said, if it can be done, and the design winds up in the OGR catalog, I'd happily pay for it (and then send it to my brother to punch out on his 3D printer!)
Thanks for any info!
