1:29 scale SP Configuration Motorized OpenRailway EMD SW 1500 G Scale Locomotive

I am preparing to design and build a Krauss-Maffei locomotive, so I wanted to practice 3-D printing an entire locomotive. I used Daniel Noree's base design for the OpenRailway EMD SW 1500 and printed a 1:32 version of it that incorporated USA Trains R22-12 motor blocks and designed a Southern Pacific light package for it. I added AirWire control and successfully ran the locomotive without problems. I then decided to scale the design up to 1:29. However, attempting to print the 1:29 parts in ABS became a problem, so I substantially modified the design and broke some of the larger pieces into smaller parts so that I could minimize the use of supports. I also vented the front air intake and front top fan cover, since there will be actual electronics inside. I tested the 1:29 version with USA Trains R22-115 motor blocks and it worked fine. You could use either the -12 or the -115 motor blocks with the 1:29 version. For the 1:32 version (which I haven't posted here), you would need to use the -12 motor blocks only.
