We need a "jaw dropping" emoji.   I have a hard time believing that the trucks I drew look that nice!  Obviously, the painting and assembly made them much better!

Version 2.0 is out in On3, Sn3, and HOn3.  
On3 and Sn3:

I have not test printed them, but there was much pain with little non-manifold errors that were tough to trace.  All three versions use the more robust sideframes which are 1 1/4" thick material on the outside.  Yep, the non-prototypical thickness on the transoms was 100% cost saving, but I think I overestimated the savings.

The holes now pass fully through the brake beams so we shouldn't have the need to drill any more out.  I could make the brake beams available as a separate bulk pack (I thought I'd done this years ago, but evidently I forgot to click the "for sale" box).

I dropped the middle hole and added two new holes for wire that are at around the right level for axle wiping.   I'd prefer to have them each only touch the back of the wheels so that 4 wheel pickup is achieved on each truck.  I've previously done this with an HO 0-6-0 for my son.  

The Litchfield revision is on the agenda now.
