I'm an long time OGRForum guy, long time Boothe Memorial Railway Society member,
But...
I'm new to the whole 3d Printing thing. I got a Bambu Labs A1 a few months ago, and I keep trying new projects... just starting to design some items. So, Don asked about the cradle and I gave it a try.
I did the cradle in two pieces, and glued 'em together to avoid using supports. Files attached for anyone who can use them...
